Hi, I am running exim 4.50 with virtual domains/users. Some of the users get their mails checked for spam by a seperate transport. Since yesterday some mails were rejected, because of problems with this transport. The following appeared in the mainlog:
---/--- 2006-02-09 13:19:49 1F7Am3-0008Uf-W1 <= [EMAIL PROTECTED] H=fmmailgate01.web.de [217.72.192.221] P=esmtp S=30388 [EMAIL PROTECTED] 2006-02-09 13:24:49 1F7Am3-0008Uf-W1 <[EMAIL PROTECTED]>: spamcheck transport output: An error was detected while processing a file of BSMTP input. 2006-02-09 13:24:49 1F7Am3-0008Uf-W1 ** [EMAIL PROTECTED] R=spamscan T=spamcheck: Child process of spamcheck transport returned 2 from command: /usr/sbin/exim4 2006-02-09 13:24:49 1F7Aqv-0008WE-Ah <= <> R=1F7Am3-0008Uf-W1 U=Debian-exim P=local S=31716 2006-02-09 13:24:49 1F7Am3-0008Uf-W1 Completed 2006-02-09 13:24:49 1F7Aqv-0008WE-Ah => [EMAIL PROTECTED] <[EMAIL PROTECTED]> R=dnslookup T=remote_smtp H=emasmail2.emarsys.net [81.223.46.30] 2006-02-09 13:24:49 1F7Aqv-0008WE-Ah Completed ---/--- The generated bounce message contains something like the following: ---/--- This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [EMAIL PROTECTED] local delivery failed The following text was generated during the delivery attempt: ------ [EMAIL PROTECTED] ------ An error was detected while processing a file of BSMTP input. The error message was: 421 Lost incoming connection The SMTP transaction started in line 0. The error was detected in line 3. 0 previous messages were successfully processed. The rest of the batch was abandoned. 421 Lost incoming connection Transaction started in line 0 Error detected in line 3 ------ This is a copy of the message, including all the headers. ------ ... ---/--- What is quite strange in my opinion is that the error is a 4xx error (which seems appropriate), but the sender got this error message and delivery has failed. I include the relevant parts of the config for reference: ---/--- spamscan: driver=accept domains= +hosted_domains condition= ${if and { {eq{${lookup pgsql{ \ SELECT spam_check FROM mail_address WHERE \ domain_name='${quote_pgsql:$domain}' AND \ local_part='${quote_pgsql:$local_part}' \ }}}{t}} \ {!def:h_X-Spam-Flag:} \ {!eq {$received_protocol}{spam-scanned}}} \ } no_verify transport= spamcheck spamcheck: driver = pipe command = /usr/sbin/exim4 -oMr spam-scanned -bS use_bsmtp = true transport_filter = /usr/bin/spamc -u "${lookup pgsql{\ SELECT username FROM domain WHERE domain_name='$domain'}\ {$value}}" log_output = true return_fail_output = true return_path_add = false message_prefix = message_suffix = ---/--- Any ideas what the problem is? This mailserver has been running for around 3 years now, without such problems. And even if there are problems during the spam check, why is the message bounced instead of just returning a temporary error? Thanks for help in advance.
