[xmail] Re: Error messages returned to sender replicated
Leanardo: Interesting find about the errors appearing not to be XMail generated - I will have to look into that in more detail by going over the logs when I can get the time. Clement: I use an IP in the cmdalias. The FQDN of the Exchange server resolves only to one IP. Xmail connects to the Exchange server through a M0n0wall firewall/NAT device that is NAT'ing the Exchange server. I don't recall seeing multiple times the same same bounce before upgrading to 1.22 (and now that you brought it up, M0n0wall is a recent addition to the network there as well). I will have to go over the logs as soon as I can to answer your other question about whether or not the bounce is seen on the Exchange side. It sounds like I will need to spend some more time with the logs and testing on this one - I will let you know what I find - thanks for all of your input!

However, XMail 1.21 does not include a Sent header; it includes a Date header. Besides that, it uses the RFC 2822 compliant date string; not a locale's date like those. 2) XMail 1.21 includes other headers (X-MessageId, X-SmtpMessageId, X-MailerServer, X-MailerError...) which are not presented in those errors. As I could see from the source code of 1.22, the same headers are included. 3) I miss the PeekTimes, section [04] of the error. Again, I could find them in the source code of 1.22. So, those error messages were probably re-generated by other MTA. Hope it helps. Regards. ___ Yahoo! doce lar.

Hmmm - ok, let me look at this a little deeper (and thanks for your input!). In answer to your questions: Exchange has its own domain, but only handles internal email (so outbound is Exchange - ASSP - (clamSMTP) - Xmail - INTERNET or inbound is INTERNET-ASSP - (clamSMTP) - XMail - Exchange). Xmail does forward the error messages to Exchange by using smtprelay in cmdalias - it does not actually have a mail account for the Exchange user, it just relays. Postmaster does receive errors as well, but they seem inconsistent with the others - I need to research this point a bit more and see if I am receiving more than 1 error to this account as well, but I don't think I am. It appears that I am not getting one email for each failure - rather, it appears to be some random number of bounce emails (sometimes 3, sometimes 5, and so on).

Thats what I thought should happen, but my Exchange users are verifiably getting multiple (it seems to be random) bounces back.

Yes - I despise Exchange, personally. However, talking the people holding the money out of using Exchange and going with LDAP/IMAP is like telling them that their father is a moron. They look dumbfounded and then proceed as if nothing was said. I host entirely on FreeBSD and I am just doing SPAM/AntiVirus filtering for this particular client. At any rate, the strange part is that each of the messages I sent IS from the same email. So, XMail is seeing two different messages (as you pointed out) but it is actually from the SAME send, so it must be getting duplicated by one of the other applications(?). So, as you mention, there is obviously something in the configuration that is causing the trouble. I will keep looking into it and report what I find for posteritys sake!

[xmail] Re: Error messages returned to sender replicated
By the way, I had no indications of this happening using 1.21 or earlier. This does not mean that it didn't for certain, but I am pretty certain that it would have come up (I was running 1.21 and maybe 1.20 from the time they were made available until the newer versions with this configuration - exchange - assp - xmail - internet). It is possible that I may have made some seemingly insignificant change to any of the players involved, though, most suspect being ASSP. I have verified that I (seem) get only one failure message back to the sender when the configuration does not involve exchange, that being email client - assp - xmail - internet. Unless I am misreading the documentation, I think this is also not the right behavior since NotifyTryPattern is set to the default, but I prefer it to a whole bunch of messages! Here is an example of the header for that: [00] XMail bounce: [EMAIL PROTECTED];Error=[The maximum number of delivery attempts has been reached] [01] Error sending message [1137796073865.135234560.61c.banshee.buehlertech.net] from [buehlertech.net].
