[Assp-user] Timeout from backup MX to email server only on detected spam by ASSP

[Philippe S. <psc...@mi...>]

Hello,

ASSP Version : 1.9.9 (14140)

I have an email server (postfix) where runs ASSP and another server on 
other network that plays the role of MX backup.
When a spam is detected comming from the MX backup, the email is well 
copied to my spam folder, but in fact the problem is that the email 
stays in the mailq of the backup server with the error message 421 4.4.2 
server.migratis.net Error: timeout exceeded (in reply to end of DATA 
command) so it is submitted again and again to the email server :(

I have this messages in mail.log :

May  2 12:20:43 server postfix/smtpd[18376]: connect from 
localhost[127.0.0.1]
May  2 12:20:43 server postfix/smtpd[18376]: A23171A3237: 
client=localhost[127.0.0.1]
May  2 12:20:43 server postfix/smtpd[16862]: timeout after DATA (0 
bytes) from localhost[127.0.0.1]
May  2 12:20:43 server postfix/smtpd[16862]: disconnect from 
localhost[127.0.0.1]

in the mailog. of ASSP :

seconds);

Here are the ASSP parameters that I believed it could fix the issue :

noMaxSMTPSessions = 'ip of the MX backup'
ispip = 'ip of the MX backup'
send250OKISP = y
'ip of the MX backup' is in the file nodelay.txt


What can I do to stop this ?

Best regards

Philippe
