[courier-users] anyone know how to resolve this
CORRUPTED MESSAGE This is the Courier Mail Server 0.45 on x.com. I received the following message for delivery to your address. This message contains several internal formatting errors. This is often caused by viruses that attempt to infect remote systems. Instead of blocking this message, it has been converted as a safe, text-only attachment that can be safely read with a text editor. This sometimes also happens when the sender's mail software has a bug that creates improperly-formatted messages. Although these kinds of formatting errors may often be ignored by other mail servers, this server detects and intercepts improperly-coded messages in order to prevent viruses from taking advantage of bugs in E-mail programs: -shane

Since the new variant of sobor is spreading, I'm getting lots of mails for non-existant users. That's not a big problem, but currently a lot of courieresmtpds keep lingering around and I'm not sure what they're doing, but they since all my mail comes from a single virus-scanning mailserver, maxperip is reached quickly. Does anyone know in what direction I should look? This is what ps looks like: daemon 735 0.0 0.0 1844 592 ?S23:19 0:00 /usr/sbin/courieresmtpd /usr/lib/courier/courier/modules/esmtp/authstart authdaemon daemon 750 0.0 0.0 00 ?Z23:19 0:00 [submit] defunct daemon 843 0.0 0.0 1844 588 ?S23:21 0:00 /usr/sbin/courieresmtpd /usr/lib/courier/courier/modules/esmtp/authstart authdaemon daemon 858 0.0 0.1 4504 1776 ?S23:21 0:00 submit esmtp dns; services3.virtu.nl (services3.virtu.nl [:::217.114.97.6]) daemon 900 0.0 0.0 1844 588 ?S23:22 0:00 /usr/sbin/courieresmtpd /usr/lib/courier/courier/modules/esmtp/authstart authdaemon daemon 915 0.0 0.1 4504 1780 ?S23:22 0:00 submit esmtp dns; services3.virtu.nl (services3.virtu.nl [:::217.114.97.6]) --- This SF.Net email is sponsored by: NEC IT Guy Games.

I'd work on getting your virus-scanning mail server a list of usernames so that it can reject mail to addresses not in the list. --- This SF.Net email is sponsored by: NEC IT Guy Games.

Thomas van Gulick wrote: Adding thousands of emailaddresses or IPs is senseless. I disagree. Accepting mail without verifying the recipient is idiocy, given the realities of the internet. If you have no other choice, then I suggest that you configure a catch-all address on your courier system, and discard mail that's sent to it. A .courier-default file with one blank line should work. Courier should not crash in the first place :) It probably doesn't. It does, however, tarpit servers that send bad commands, including directing mail to non-existent users. If your virus scanner batches mail (and it probably does), legitimate mail is going to be delayed because of the bad mail. The remote server might be just giving up and disconnecting. Furthermore, the virus scanning mailserver is my provider's, and they probably will upgrade their virusscanner, but again, this doesn't solve the problem courier is giving me. It's strange it just sits there doing nothing, getting defunct even. It's doing what it was designed to do. It's not courier's fault that you haven't considered the consequences of mixing two technologies that weren't designed to work together. You have options to fix the problem, though. ...and please keep replies on the list. :) --- This SF.Net email is sponsored by: NEC IT Guy Games.
