[Mailman-Users] Mailman postings deferred by Yahoo
My hosting company tells me that the mail logs indicate that the majority of Mailman's messages to Yahoo addresses return a deferred message. Here is the complete message: [EMAIL PROTECTED] R=lookuphost T=remote_smtp defer (0): SMTP error from remote mail server after initial connection: host g.mx.mail.yahoo.com [206.190.53.191]: 421 4.7.0 [TS02] Messages from 216.104.33.122 temporarily deferred due to user complaints - 4.16.56.1; see http://postmaster.yahoo.com/421-ts02.html All of my outgoing email uses the same server located at 216.104.33.122 and any single email that I send to any Yahoo address using any client is received just fine. My Mailman list is very small with 20 members and only 3 Yahoo addresses and the user complaint thing is bogus. This is a golf list for crying out loud.all of the members want to know what their tee times are for Saturday! All of Yahoo addresses have the same issue, even my own which I added to the list for testing. And I said majority, because 1 in 15 or so messages will miraculously come through. Does anyone else have any experience with this, and is there something that I can do on my end that would help?

Re: [Mailman-Users] Need ability to allow emails with specificsubject line
Well I found a workaround for my problem. I used in the CGIEmail, as was suggested yesterday, to just use an email address in the FROM line of my CGI form file that was accepted by the email list and it worked famously. I don't know why I had not thought of that but I appreciate the insight and direction that was given. Thanks so much for all the help and the responses. Jason, thanks for all your help and the code that you gave. I may be using it in the future. Thanks so much.

And this form is setup to use the POSt method, but can be changed to use GET... Let me know if you have any questions about it. And if you improve it, definitely let me know...

Re: [Mailman-Users] Mailman postings deferred by Yahoo
Thank you for the response. I have spent time testing individual mail to the same addresses from the same source and I am successful. What I failed to note in my posting is that this occurs when the mail is going to multiple addresses as in a normal post. If I go into my list and turn everyone off except for my Yahoo address, it will work EVERY time. Then I go back in and turn all of the addresses back on and the Yahoo addresses get deferred including mine. I'm not blaming Mailman...I'm just asking if there is something about Mailman that I can change that will overcome this. Changing anything about Yahoo would be like changing heaven and earth. Surely, someone else is experiencing this issue.

Re: [Mailman-Users] Mailman postings deferred by Yahoo
This sounds like an anitspam tactic to me. Messages addressed to multiple recipients are deferred, since a lot of spammers won't try sending a deferred message again; It's not worth their time or resources to keep track of deferred messages, and then go back and retry them. A legitimate mail will go through, just not until your MTA sends it a second time, upon which their servers will most likely accept it.

I have also tried getting my servers whitelisted and to sign up for their feedback loop but all to no avail. If your hosting company is running exim as their mta, ask them to run one of the following commands every 5 minutes are so: exim -Rff yahoo.com or exim -qff Those are the commands that I use to get my clients' posts pushed through to yahoo accounts in a relatively short time. Running VERP is not a viable alternative for those of us who host multiple mailing lists due to the resource hit that the server takes. I think the long term solution is to get your members signed up to your list with another e-mail address. If only yahoo's free email users knew how yahoo is interfering with their mail delivery.

Yes. I am on a shared server. It seems that Yahoo picks up on the fact that this is going to multiple recipients (apparent 5+ raises the flag).

Yes, it might overcome this problem, but you'll get another, even worse one: maintenance problems.

Re: [Mailman-Users] Mailman postings deferred by Yahoo
I guess the point of this and other messages regarding spam is that Yahoo is being very cautious and erring on the side of protecting their clients. Meanwhile, in my Yahoo mail account this morning, I flagged as spam a message supposedly coming from Yahoo mail offering me random prizes, an offer for me to claim some cash from Nigeria, and some porn. All my list is trying to do is to communicate with 15 golfers about what time they are supposed to show up to play on Saturday. Only 3 of those are Yahoo addresses.

Our server sends out a few dozen mails a day on the low traffic lists to a few hundred on the high traffic ones. Any greylisting that is half way sanely implemented should know after the second mail that the server is a legitimate sender. I don't know what they actually use to base their decission on, but what ever it is, it's not one of the standard ways. A look at http://help.yahoo.com/l/us/yahoo/mail/postmaster/postmaster-15.html I've read that already and i comply with all but the Can-spam thingy (no idea what that is) and the Domain-Keys (too lazy to set them up).

Mail abuse-admin(AT)cc.yahoo-inc.com [...] Unfortunately, your message was sent to us as an attachment or html document. Due to security purposes, our custom messaging system is unable to access attachments or webpages and we will need you to cut and paste plain text information, as opposed to html format or sending it as an attachment. We apologize for the inconvenience. --- I really wonder if anyone is reading the mails at yahoo or whether they just use a bot that sends back an canned answer based on some key words. Otherwise someone would have noticed that the logs i mentioned as being attached are missing. Oh yes, since i send the log inline, i haven't heard back at all.

(Mailman is (was?) not friendly to domain keys of non-owner posters, but in the case of an announcement list having the host sign the post should work fine.) I don't know whether i should do domain keys. Sofar it was never a problem that we got tagged as spamers, it might be worth it if more ISPs start to filter based on these. PGP is definitly not an option. We send out way over 100k mails per day over mailinglists (at some days it reaches even 200k mails/d). Signing all of them on the server would produce too much load.

Actualy, i'm not angry at them, because they try to get a solution to the spam problem, but rather that they are also hitting legitimate users and refuse to talk about possible solutions. I care about the users of the mailinglists i manage. If i see that anyone has a problem that might be on my side, i try to contact them to figure out how to solve it. It was a lot of work in the first months, but the result now is that our mail setup works very well and that even strange and broken setups on the receiving side have little or no effects.

Re: [Mailman-Users] Mailman postings deferred by Yahoo
Quoting Larry Stone ([EMAIL PROTECTED]): I'm not blaming Mailman...I'm just asking if there is something about Mailman that I can change that will overcome this. Changing anything about Yahoo would be like changing heaven and earth. Surely, someone else is experiencing this issue. Turn on VERP or full personalization. That will force mailman to generate a separate message for each recipient and Yahoo will see several messages each addresses to one recipient rather than one message addressed to multiple recipients. VERP does not necessarily solve the issue. I have VERP running on my lists, and yahoo is still deferring me and delivering to the spam box when they DO deliver. dd -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=showamp;file=faq01.027.htp

Re: [Mailman-Users] Mailman postings deferred by Yahoo
-Original Message- From: Stephen J. Turnbull [mailto:[EMAIL PROTECTED] You're welcome to like the attitude, but it's really just the flip side of Yahoo's. The problem is spam, not Yahoo, and Yahoo serves a clientele that in general cares more about spam getting through when they don't want it than ham not getting through when they do want it. If you really want to stick it to Yahoo, they claim that they respect authenticated mail. PGP sign everything that goes through your server. If they're serious about delivering mail that their users want, that had better be good enough.

Our server sends out a few dozen mails a day on the low traffic lists to a few hundred on the high traffic ones. Any greylisting that is half way sanely implemented should know after the second mail that the server is a legitimate sender. Well, maybe. That is harder than it sounds to scale, though. The problem is that Yahoo has a lot of MXes, each handling hundreds of thousands or millions of messages per day, and they're going to need to propagate the greylist database to all of them somehow. It's a solvable problem, but nontrivial. If you're using exim -qff, you also may be running into a problem of hammering on their MXes too frequently; many greylisting algorithms don't like that. BTW, do you think they're lying about the user complaints? I'd rather say [Yahoo] have no clue at all. The problem that Yahoo faces is that not only is their hardware distributed, so is their wetware. It's a lot easier for one person to handle a few clues about the easy problems that one person can handle than for an organization to deal with many clues about the much harder problems of scaling to Yahoo size. I don't know whether i should do domain keys. Sofar it was never a problem that we got tagged as spamers, it might be worth it if more ISPs start to filter based on these. PGP is definitly not an option. We send out way over 100k mails per day over mailinglists (at some days it reaches even 200k mails/d). Signing all of them on the server would produce too much load. Domain keys are per-message cryptographic signatures, too. And as for 200K mails per day, is that 200K *posts* per day, or more like 2000 posts per day going to 100 recipients each, or even better yet, 200 posts/day going to 1000 recipients each? And which would you rather do: save a few CPU cycles, or reliably get your mail through? Maybe the usual variants on PGP are too expensive, but something weaker will do until the spammers catch on, by which time you can hope that everybody has enough CPU, and so on. I know that the conventional wisdom that signing mail is very expensive is well-justified, but on the other hand you have to remember that there's a difference between very and too expensive. BTW, of course it turns out that Yahoo doesn't implement the standard that it sponsored (DKIM), but rather its own legacy variant.

Note: The following is an incoherent rant from a deranged and totally frusted person. You've been warned. I'm getting the deferral based on customer complaints message. I looked it up on Yahoo's web site, and I followed a link to Does Yahoo! Mail offer a feedback loop program to help senders minimize complaint rates?. I thought good, I can sign up and find out who's reporting my mail as spam. Then I read further and found To participate in the program, senders must sign their outbound emails with DomainKeys (DKIM is not currently supported). This is the second time in recent weeks that some large mail service has used it's 600 lb. gorilla status to try to coerce me into something, and I don't like it. Actually, I don't care that much about Yahoo, because they do seem to accept my mail. My real complaint is with Microsoft and Hotmail. Several weeks ago, Hotmail started discarding some of my list mail, this quickly escalated from some to most to all. Note that they didn't reject it. Their MXs accepted it, but it never got delivered to any recipient, regardless of any whitelisting the recipients applied. I eventually found my way to https://support.msn.com/default.aspx and submitted a report via the form linked as Sender Information for Hotmail Delivery. I got a response to that (to their credit, they always responded) suggesting I add SPF records in DNS (more 600 lb. gorilla tactics), and giving me a hotmail.com address to send sample messages to, and requesting that I inform the responder of the subject header of any messages I send. I tried to do this. I don't know what happened to the message I sent to the hotmail.com address, but my reply to the support rep bounced per Action: failed Status: 5.1.0 Diagnostic-Code: smtp;554 5.1.0 Sender Denied I took great pains to always use my postmaster address in reports and replies. I went through several iterations of submitting forms, receiving replies and being unable to respond to the follow-up questions in the replies (always with the same reject as above).

(Mailman is (was?) not friendly to domain keys of non-owner posters, but in the case of an announcement list having the host sign the post should work fine.) Using PGP is not going to help, but DomainKeys may. The administrator of the mail server in question could also sign up for the Yahoo! feedback loop mechanism (see http://help.yahoo.com/l/us/yahoo/mail/postmaster/postmaster-30.html). I've recently started working at the University of Texas at Austin, and it looks like I'm going to be doing some of their postmaster work. I've been trying to get our mail servers signed up for various feedback loop mechanisms at major providers around the world, as well as subscribed to at least one or two bonded sender type programs. We're one of the largest public research Universities in the world with ~50,000 students and ~20,000 faculty and staff, and I can tell you from first hand experience that this is a painful process. I filed our request with Yahoo!, but have not yet heard anything back. We're on the AOL feedback loop, and getting quite a lot of reports about our users, many of which are hitting the report as spam button for messages that were forwarded to them from their mail.utexas.edu account, which means that AOL thinks we're sending them spam, when in fact we're just forwarding mail for a given user, which just happens to be spam. We're also on the feedback loop for TimeWarner/RoadRunner, discovered that Gmail doesn't have any such service, and the people at NetZero/UnitedOnline really have no clue -- they don't get the fact that UT actually is their own ISP, we are our own phone company, we are our own power company, we are basically our own city and we provide all of our own various services, for a mid-size city community of about 70,000 people. Oh, and Windows Live (you can't call it Hotmail anymore) requires that you have a registered Windows Live ID before you can sign up for their equivalent Smart Network Data Services program. One problem with trying to get on all the various feedback loop processes, and obtaining service from a bonded sender program, is that they all have different requirements. Some require SPF, some require Sender ID, some require DomainKeys, some require DKIM, some require that you sign up for service with ReturnPath/SenderScoreCertified, some require Habeas, some require GoodMail, and some require service with any of several other such services. No one can do all of these things, and many people find it difficult enough to do just one or two. This is turning into a situation worse than TMDA, where the recipient site can't be bothered to do any real work themselves, so they force everyone else to do their work for them. -- Brad Knowles [EMAIL PROTECTED] LinkedIn Profile: http://tinyurl.com/y8kpxu -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=showamp;file=faq01.027.htp

Our server sends out a few dozen mails a day on the low traffic lists to a few hundred on the high traffic ones. Any greylisting that is half way sanely implemented should know after the second mail that the server is a legitimate sender. Yahoo! has demonstrated that they don't understand the greylisting concept anyway, so this is unlikely. They use a shared pool of outbound messages through all of their outbound mail servers, so you're pretty much guaranteed that the same message will never be touched by the same machine twice. This ensures that their outbound mail will never be received by a site that implements a strict per-machine greylisting policy. Only a looser network-level greylisting policy, will have any chance of working with Yahoo, and even then it won't work very well -- they just have too many outbound machines on too many different networks. I don't know whether i should do domain keys. Sofar it was never a problem that we got tagged as spamers, it might be worth it if more ISPs start to filter based on these. PGP is definitly not an option. We send out way over 100k mails per day over mailinglists (at some days it reaches even 200k mails/d). Signing all of them on the server would produce too much load. This is the fundamental problem with creating or verifying all crypto signatures of all mail passing through a server.

Actually, fighting spam is one area where AOL has historically done pretty well. I know that it was the biggest part of my job when I was the Sr. Internet Mail System Administrator there, and I took my job very seriously. We did a lot of things to prevent our customers from spamming, and we did a lot of things to try to protect them from getting spam.

Where AOL has fallen down is by making the Report as Spam button far too easy to hit, and doesn't require any kind of confirmation or anything.

Yeah, but SPF/SenderID and DKIM/DomainKeys are not the right tools to be forcing everyone else in the industry to be using to achieve this goal. You might as well force everyone to use only 24lb sledgehammers when they want to fasten any two objects together, and ignore all other fastening technologies like screws, glue, etc The DKIM guys did their homework -- they identified the weaknesses in SPF, and they found ways to avoid pretty much all of them. Problem is, they brought out the crypto-nuclear weapons to use against the spammers, and they forgot that the spammers are like cockroaches, and they're the only ones who'll be left on this planet when the nuclear weapons actually get used. You can't have it both ways. If AOL's database is organized by IP, when you get filtered, you will get filtered by IP. If you want Yahoo to distinguish your diligent (and/or lucky) domains from the less so, you're going to have to give them domain keys so the good ones can't be spoofed by the bad ones (or worse, by the bad guys themselves). I don't think you can effectively protect these assets by domain. Among other things, there are far too many places out there that might have a valid need to send e-mail on my behalf, using my address, and any domain-level protection mechanism would almost certainly break that aspect of e-mail. There go all your e-mail greeting cards, there go all your e-mail notifications of birthdays or other events, and a whole host of other things. You can't even protect these assets completely by IP address. If the spammers can get friendly with an ISP so that they can advertise bogus routes to your network, then they can send out mail from their machines using your IP addresses, and all your IP-based security mechanisms go out the window. The mail will be treated by the other end as if it really had been sent by your mail servers, and then they'll go away in five minutes. But the damage has already been done -- the spam has been sent, and someone else has been blamed. And all those ephemeral routing advertisements never get logged anywhere, so no one would ever know that it wasn't really you that was sending e-mail from that IP address. You don't have to like it; I don't like it at all. But it's not very useful to propose that the 600-lb gorillas stop targeting the middlemen, nor to complain about gorillas that ask for authentication of every domain that wants to clear its reputation with the simians' systems. I don't mind them targeting the middleman. I just want them to target using the appropriate tools. I want them to have enough intelligence to know when a user has set up forwarding on our system to their system, so that when a spam message comes in and the user clicks report as spam, they can look through the headers of the message and avoid blaming us for sending spam to that user, because we were actually just doing what the user asked us to do. The alternative is to just refuse to forward e-mail anymore. And I don't really like that. Oh, and btw, this also affects mailing lists, because all the low-level mechanisms for forwarding e-mail are functionally identical to operating a mailing list. Not until we can provide an alternative that looks like it might work. They've got the money. Let them pay to come up with something that will actually work. -- Brad Knowles [EMAIL PROTECTED] LinkedIn Profile: http://tinyurl.com/y8kpxu -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=showamp;file=faq01.027.htp
[Mailman-Users] Mailman not sending mail to list members
Hello, I am running Mailman version 2.1.6 and recently had to move my servers from one data center to another. This necessitated a change of IPs. Since the move, Mailman has refused to send out posts from my lists. Mail gets to the host and is redirected through aliases to the proper location, but then seemingly disappears. To be truthful, mail from the test list does show up very sporadically, sometimes hours later. But ... 90% of the time .. nothing happens. I am also running Linux ebony.zuka.net 2.6.9-11.ELsmp #1 SMP Wed Jun 8 17:54:20 CDT 2005 i686 i686 i386 GNU/Linux This is CentOS release 4.1 (Final) This is Perl version 5.008005 (5.8.5) This is MailScanner version 4.63.8 I have checked all the logs and can find nothing that sticks out. Nothing, other than the IP numbers have changed after the move. I am stumped so I am hoping someone might be able to suggest somewhere to look and some sort of troubleshooting that I may have missed.
