[courier-users] Fallback to backup (secondary) MX
Hello courier users. I have a problem with courier server - especially SMTP module. I send a mail through transparent mail proxy on our firewall. When the primary MX of recipient's domain in unreachable, i get this reply from relay: 421 4.4.1 Unable to contact destination Other MX records aren't tried and the mail is deferred. I'd like courier to contact backup MX'es before deferring the mail. How can I achieve this? Thank you very much for answer.

You can achieve what you want by learning a little bit about SMTP first. If the above message is received in response to a delivery attempt, the message is interpreted as an indication of a temporary failure, and to try again later. That is later, and not try another mail relay now. Do to otherwise would be a behavior more akin of a spam generator, and is likely to get you blacklisted as such. pgpjZFLt09ERB.pgp Description: PGP signature

The issue boils down to the fact that SMCs ('stupid mail clients') are far

To be honest to MUAs, we should note that to properly handle 4xx
responses one needs to manage a queue, which in general is not
their job (although trying once more would suffice in this case.)
All SMCs are MUAs. Some MUAs are also SMCs ;-)
Connections using authenticated SMTP are also likely to be SMCs and thus
require such an exemption.
So the equation RELAYCLIENT = MUA still holds.
No question about this. If courier is going to implement a content
filtering exemption for RELAYCLIENT hosts, my point is that it should do
likewise for MUAs connecting through authenticated SMTP.
but what with the rise of various anti-spam
technologies such as SPF I would expect that there would be an increase in
the use of authenticated SMTP.
Yes, large ISPs are better off if they stop relaying for _local_
addresses w/o auth. Fastweb, for one, is a large Italian ISP who did so.
Those who don't will get on spamhaus or MAPS every now and then, I suppose.
I've been out of the ISP business for years, working only as an occasional
consultant for a regional ISP in Texas, but I do know that any ISP with a
substantial number of non-techie customers that started requiring auth SMTP
and stopped relaying for local clients had better have all their tech
support folks on notice to work overtime for at least a couple of weeks!
It's a funny thing about email. People think of the Web when they think of
the Internet, and if their web service goes south, they get pretty unhappy,
but if their email quits working, they come after you with a rope grin.

[courier-users] Adding TO when delivered to ALIAS
Say you have a single mailbox (virtual or not, doesn¹t matter): [EMAIL PROTECTED] Now, say you have in the file /[courierpath]/etc/aliases/yourdomain.com some aliases like: [EMAIL PROTECTED]: [EMAIL PROTECTED] [EMAIL PROTECTED]: [EMAIL PROTECTED] When courier receives mail to be delivered to yourdomain.com, it does its normal routine and finds that the delivery is for an alias, and then it sends it to the actual email for the alias definition. That¹s all fine. Works great. However, sometimes people (mostly friggen spammers) don't include the TO email address in the email. This gets left out somehow. However, it still gets delivered (so courier obviously knows!). When you receive the email that was sent to an alias, it goes to your spamdrop mailbox, and you cant figure out which alias it was sent too. Even while examining the full internet headers. So... My question is... There a setting I am missing? Somewhere the headers can be written too to add the actual destination address? Or maybe something else. Ideally I would have liked the aliases files to handle something like: [EMAIL PROTECTED]: bizzwang [EMAIL PROTECTED] [EMAIL PROTECTED]: wingding [EMAIL PROTECTED] Then, when its delivered, you would see it as a name to the mailbox address. I'm a nut with aliases... Same with some clients. We make a new alias for any new service, or site, or account created that needs an email box. I then monitor my spam intake, and see where they sent spam too (which alias). That way I know who the frelling idiots were who sold my email out. Then I drop that alias and say goodbye to the spam from them. However, when that spam gets delivered lacking the needed headers... I cant for the life of me figure out what alias it was delivered too! AGH! Like lately these lame MS Security Patch virus emails... Grrr. Help? Please? -Randall Shaw --- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id%62alloc_ida84op=click ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

I have read the courier docs but they I do not think I followed it very well. Any help/suggestions would be appreciated. :) You can do just about any filtering you want within what Courier calls a global filter. You can do a man courierfilter to get info about this. In a global filter, you have access to all the headers and body text of a message, and you can use that info to implement your chosen filtering mechanisms, which can then be used to reject unwanted messages. The setup is a bit complex for global filters, and people have written tools to help simplify this. One such tool is the Perl package called Courier::Filter. Another is the Python package called courier-pythonfilter. Courier provides another filtering mechanism called local filters. These are applied later in the message delivery process, after the global filters have provisionally passed the messages. You can use maildrop or other similar packages to aid in this local filtering. Do a man localmailfilter for info. I should warn you, however, that in addition to understanding how Courier delivers messages, you also need to have a fairly extensive knowledge of internet protocols in order to have any kind of success at filtering spam using your own, home-grown methods. You need to look at the RFC's (official internet protocol specifications) and understand what is _supposed_ to happen when email is being delivered before you can begin to understand how to block the illegal stuff. A good RFC to start with is RFC-2821. If you want to punt on all this, you can make use of software like SpamAssassin and TMDA (to name two out of many), which are pre-written packages that work with most MTA's. If used correctly, these do a fairly good job at spam protection. But I still recommend you read and understand (at least at a high level) RFC-2821 and other similar documents. -- Lloyd Zusman [EMAIL PROTECTED] God bless you. --- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id=2562alloc_id=6184op=click ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users

[courier-users] Clearing the MailQ and rejecting...
(I read the man page on these, very little help as always) Isn't there a command to clear the ENTIRE mailq ? Cancelmsg just does one at a time. I want to clear out an entire queue. Main reason is, spammers are sending spam to our users, but it gets bounced because spammers are idiots. However, since it bounces, and spammers use faulty from and return addresses, this crap gets deferred into a massive backlog that just goes on for miles and puts our server into a tissy of trying to return it. I took the most obvious hog, which is @com.com and tried all these in etc/bofh: spamtrap @com.com badfrom @com.com freemail @com.com ...it seems to do nothing to prevent them from filling up the mailq and making our maillog a good 50mb a day.

Re: [courier-users] aliasdir/Maildir mbox file.
I can promise you that 1) the only authentication methods I am using are: authmodulelist=authcram authuserdb authshadow and 2) I have only ONE userdb entry (read: 1 file in etc/userdb/ with 1 line in it) and the address looks nothing like *alias*, nor does it have the home directory of /usr/lib/courier/etc/aliasdir/. From what I understand of how courier figures out how to deliver a mail, there's no reason it should be writing to this file.

Re: [courier-users] aliasdir/Maildir mbox file.
Well... Wow. That does sound strange! Thought surely you had an entry in a user database... But I guess that is surely not the case. Sorry, but that is all I had, maybe one of the gurus can figure it out for you. Sounds like a fun problem! Well, maybe not fun for you... -Randall Shaw --- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id=2562alloc_id=6184op=click ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
[courier-users] How to throttle message sending (as an abuse prevention) ?
Hi, is it possible to throttle the number of mails sent by users to prevent the abuse of a mailserver, e.g. to allow people only to send one message per minute? Thanks again for your attention!

The trouble with using a .courier-default file (as I've sadly discovered) is that you end up receiving all email, even those which can't possibly be delivered. Of course, the emails that can't be delivered get bounced; but my experience is that the DSN's are undeliverable and so sit in the queue for ages. --- This SF.Net email is sponsored by: SourceForge.net Broadband Sign-up now for SourceForge Broadband and get the fastest 6.0/768 connection for only $19.95/mo for the first 3 months! http://ads.osdn.com/?ad_id=2562alloc_id=6184op=click ___ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
