so it is easier that temporary network problems end up being hidden by its caching. - Davide But why should a temporary network problem cause any issue in the first place, unless that problem is a bad DNS entry? Network connectivity issues during a DNS query should at most cause a delay in sending the mail, but the mail should eventually get through without user intervention. I'm still concerned that your fall back to A after MX timeout could cause a permanent delivery failure (trying to send to the host pointed to by the A record, potentially hitting an SMTP server that would refuse the delivery) when the failure should only be temporary (can't get any results from the domain's DNS servers due to a network failure somewhere while trying to lookup the MX record). Admittedly, this would be a _very_ small window of opportunity, but still possible if Xmail handles this as you suggest. - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

Next one would still try to re-fetch MX records. Still, you would think a timeout on a MX record lookup (from every domain DNS server) should also result in a time-out when looking up an A record. If you can get an A record without a timeout, then you should be able to at least get a nodata response on MX lookup. Good that Xmail does not cache the A record, but falling back to an A record after timeout on MX lookup still seems like a bad idea. - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

[xmail] Re: External POP3 on SSL
While I've never used Stunnel for a SSL POP3 client, a quick search
brings these instructions:
For [*nix] e-mail clients which don't support SSL:
1. install stunnel on the client machine;
2. if you want to check the server certificate (optional, but
recommended), copy the server CA certificate in
/usr/local/ssl/certs/CAcert.pem and:
cd /usr/local/ssl/certs/
ln -s CAcert.pem `/usr/local/ssl/bin/openssl x509 \
-noout -hash CAcert.pem`.0
3. run stunnel using the command (tipically during the startup):
stunnel -c -v 2 -d 143 -r imap_server:993
stunnel -c -v 2 -d 110 -r pop3_server:995
where the option -v 2 has to be specified only if you executed the
previous point.
4. Configure the e-mail client so that it accesses the imap (or pop3)
port of localhost.
For [Windows] e-mail clients which don't support SSL:
1. install stunnel on the client machine;
1. download winstun.zip
2. extract ssleay32.dll, libeay32.dll and stunnel.exe in the
same directory (if you prefer, the dlls can be moved in \windows\system).
2. run stunnel using the command:
stunnel -c -d 143 -r imap_server:993
stunnel -c -d 110 -r pop3_server:995
3. Configure the e-mail client so that it accesses the imap (or pop3)
port of localhost.
It appears that Stunnel is indeed the solution.

Paul,
Short answer - *As far as I know* Xmail's pop3 retrieval does *not*
natively support SSL. This means you'd have to use an external SSL
provider (such as stunnel).
A more detailed answer is somewhat beyond my capabilities, as I use
stunnel for inbound (server-type) connections, not for outbound. But I
do know stunnel can support outbound (client-type) connections - and I
*think* there was an example on their site on how to set it up (but it's
been over a year since I was there, so)

Ok, dude, that was less than helpful, so perhaps you didn't understand the
question or the situation. Let me try to clear it up for you...
Short version:
Gmail is the HOST, xmail is the CLIENT.
Long version:
Gmail requires an SSL connection for POP3 access. Any other mail clients
I've used require some special options for connecting to the POP3 server
over SSL. Now, I'm not a network engineer or even have any more than a
slight idea of how this works, but this tells me that it may be an entirely
different communication protocol than just open up a port and start sending
commands.
Since Xmail is acting in the place of any other mail client (Outlook,
Eudora, etc.), I would assume the same options for SSL would apply. Is this
true? If this is not the case, do I just specify port 995 as part of the
POP3 host address and all is good? Are there any special instructions that
I overlooked during setup to retrieve mail from a POP3 host that requires an
SSL connection?
I don't want to use SSL for what xmail is serving, I need to use SSL to
retrieve my external POP3 mail as the host requires it. From the
information I got from their website (http://www.stunnel.org), it would
appear that I would use stunnel to encrypt the connection between my xmail
server and it's clients, not the other way around where xmail is the client
and the POP3 host is already encrypted. If this is an incorrect assumption,
perhaps someone can trow me a bone and give up a little more information on
how to accomplish what I'm trying to do.

[xmail] Re: RCPT TO smtp filter.
Yes, they are currently triggered once for all, hence my request ;) I was trying to figure out of there's any way to handle it with external auth, but couldn't come up with anything. To make it somewhat compatible with current SMTP filters, it could just keep appending the new address to the message file. Your script would just need to know the last address is the new one, although adding a mail from and rcpt to macro might be just as easy, and less overhead for the filter to deal with. A helpful additional macro in either case would be an error count, to track the number of bad addresses the MTA has tried so far. I don't know if you could do it in a post data filter, since there's no option but to send a single rejection at that point. But after each RCPT TO, you could opt. to accept or reject that address for any given reason, where Xmail currently only does so based on mailbox size, or if the mailbox exists, etc. CLEMENT Francis wrote: I think smtp filters are currently triggered once for all rcpt, not for each rcpt !

[xmail] Re: Misdirected Bounces
I agree, it is best to have the secondary/scanning server know what accounts are real or not, but this isn't always practical to enforce. Still, in the case that the secondary does attempt delivery to a non-existent account, as long as it's already decided that it's not a virus, the mailbox that it'll be sending the bounce message to is much less likely to be a forged, and valid, address... and this is what Spamcop is really trying to stop: Bounce backs, predominately from virus' that forge the sender using a randomly chosen, but real, address. Eliminate the virus, and you eliminate the majority of the problem. Bill Healy wrote: But if there is a secondary or virus scanning only server that is a relay for another server it has no way of knowing which accounts are valid and it will accept all mail for handled domains. Then when the secondary MX or virus scanner tries to deliver the message to the primary mail server it will at that point find out if the mail is to a valid account. If it's not valid then the server trying to make the delivery will generate a bounce message back to the sender, that's the problem spamcop is trying to stop. The load on my spam and virus scanning servers that front end for other mail servers has significantly decrease now that I verify who the mail is going to before any spam or virus scanning. I'm not using xmail as my front end server for scanning, I'm using a dedicated server with MailScanner http://www.mailscanner.info/ to scan for virus, spam, phishing, banned attachments, among other things before being passed on to the Exchange and xMail servers.

Hey Dale, One problem with filtering in filters.in.tab, is that you'll end up scanning the message once for every recipient on the list... so you could end up scanning the same message a number of times over.

[xmail] Re: CLAMAV is the culprit... WAS Sending to multiple recipients
They should be near the same, however, I don't know if the spool files
accessible via normal mail filters (filters.in.tab/filters.out.tab) have
the {ra=real-address} info on the RCPT TO: line like you get with smtp
message filters. They may, but I honestly haven't used them much since
Davide implemented smtp filters.
The few things you need to keep in mind; exit codes that your filter
will return will be different from message filters to smtp message
filters, and many of the macros available in message filters aren't in
smtp message filters. It's also important to note that smtp filters are
running real time.. that is, during the smtp communication with MTAs, so
they need to be quick. In short: No, most standard filters won't work
well as an smtp filter without modification.
Now, about clamscan. Unfortunately, clamscan is _much_ slower than
clamdscan. Because of this, I wonder if, when receiving a shed load of
messages to filter all at once when you have a large cc list, the filter
would time out, somehow leaving things in a state that let Xmail decide
to dump or not deliver the message.
So, my first suggestion would be to get clamd and clamdscan up and running.

I'm not sure if this is what he's refering to, but most (all?) of the
ClamAV filters I've seen posted for Xmail will not catch all test virus
samples from places like http://www.webmail.us/testvirus
In order to catch all of them, the filters need to strip Xmail's special
header information (strip everything up to and including MAIL-DATA),
and add a Return-Path header to the top before scanning.

[xmail] Re: messages to yahoo and or hotmail does not get delivered
I think most web browsers will cycle through A records until it finds one that works. I see no reason why an MTA shouldn't. RFC 2821 Section 5 says: When the lookup succeeds, the mapping can result in a list of alternative delivery addresses rather than a single address, because of multiple MX records, multihoming, or both. To provide reliable mail transmission, the SMTP client *MUST* be able to try (and retry) each of the relevant addresses in this list in order, until a delivery attempt succeeds. To me, this implies that Xmail should be trying the alternate A records. I do know that if any MX records exist for a domain, you should never fall back to the A record for that domain -- even if you're unable to connect to them. Does Xmail obey this? Leonardo Fogel wrote: Although yahoo.com has 4 mx records and each mx record has 4 A records: yahoo.com. ... MX 1 mx1.mail.yahoo.com. yahoo.com. ...

A 66.218.86.156 xmail tries only one A record for each mx record, in case of successive failures. This is by design. Please, is it an RFC recommendation? I understand the multiple A records are intended to provide load balance, but what is an mta supposed to do in case of failure? Shouldn't it try all A records till success?

Davide, When mail is sent with a bad EOH, (no double CRLF separating the header from the message body), it appears that the message file available to a post-data filter doesn't have this corrected.

Jeff Are you stripping all attachments with ASSP? If not, how does clamSMTP react to large (5MB) attachments? Does it just not scan them, or does it risk a time-out? I currently use a combination of blacklisting and greylisting (and of course some white listing) in a pre-data filter, so actually very few viruses do make it to the scanner. Though some aggressive viruses have managed to pound their way through the greylist before they end up on a blacklist. clamSMTP would require me to do all my antispam with something like ASSP, as you've suggested, and possibly complicate things like shutting off antispam and/or antivirus at a per user level (something we do quite often) - but it is something to think about. Still, the perfectionist in me still wants to get my script working well (and fast - many of our users tend to send large attachments via email).

Second question: is there any way to configure XMail to block any unauthenticated request from untrusted IP addresses (not in SMTPRELAY.TAB), but still allow mail from the Barracuda to come in (obviously the Barracuda is in SMTPRELAY.TAB) and allow our users to relay with authentication? Thanks in advance for any advice and/or insights! Kirk You could probably make a simple pre-data smtp message filter that just rejects the message if the user is not authenticated. -John - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

Since most (not all, as has been pointed out here in the past) dynamic addressed machines are covered by terms of service or acceptable use policies that prohibit the running of servers, a case can be made that these machines should not be sending mail directly to mail servers (other than the ISP responsible for their connectivity). And, of course, if there are specific machines that are running mail servers, they can avoid such a block in two ways: 1) Getting a static IP address from their provider so that you can whitelist the address 2) Getting non-generic RDNS assigned by their provider [...] Of course 1. and 2. are not feasible for about 99% of broadband users who want to run a legitimate mail server. Static address and RDNS is out of the question (an ISP usually charges a busisness rate for this) -Lac I've been grey listing suspect servers, returning a 4xx error in a pre-data filter on the first try, then letting it through on the next, assuming enough time has passed. This does complicate things, as you'll need to track the senders email address and IP address, and the rcpt(s) address in a database -- but it seems to be working well with few false positives. It can potentially delay a good amount of mail however, depending on how you decide what's suspect or not - and gets even more complicated if you have any backup SMTP servers. - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]

[xmail] Unable to create/remove directory
On one of my Xmail servers (win32 1.18) with ~50 domains, when adding or removing a domain I always seem to get an error.

Also, on my other Xmail Win 32 servers (1.17/1.18/1.20), it seems that when deleting a domain with a large number of users, with a large number of messages still in their mail boxes, I will also get Unable to remove directory... but again, the directory is removed.

Found the domainadd problem the cmdaliases directory was missing on that server for some reason. Also looks like the domaindel problem on the other severs may have been related to the domains being removed not having their own directory under the cmdaliases directory, since they were probably added long before xmail used cmdaliases... So I wrongly related this to there being allot of mail left over (there was)... It was just that the domains were that old. Chalk another one up for user error.
