Hi,
I have an authenticated SMTP, based on postfix 2.9.6 from debian
repository with spamass-milter (for reduce outbound spam) and
milter-greylist (for rate limit) and Dovecot SASL for users backend.
It works perfectly.
I wrote a simple "parser" for postfix logs, when an user send spam I
can block his account and notified to him the abuse:
This is the log where the spamass-milter block the messagge:
Jan 20 15:13:43 smtp-container postfix/cleanup[16784]:
3f7FGt5y0yz1Px8: milter-reject: END-OF-MESSAGE from
1-2-3-4.v4.it[1.2.3.4]: 5.7.1 Blocked by SpamAssassin;
from=<[email protected]> to=<[email protected]> proto=ESMTP
helo=<[192.168.5.104]>
thanks to the queue id (3f7FGt5y0yz1Px8) I can identify the
sasl_username that send the message.
But when it is milter-greylist to block the message the log is
different:
Jan 20 16:43:49 smtp-container postfix/smtp/smtpd[18383]: NOQUEUE:
milter-reject: RCPT from 1-2-3-4.v4.it[1.2.3.4]: 451 4.7.1 Message
quota exceeded; from=<[email protected]>
to=<[email protected]> proto=ESMTP helo=<[192.168.5.104]>
As you can see there isn't any queue id, the messagge is reject
before being placed in the queue and in the log there isn't any
information about the sender username (necessary to my parser).
Is possibile to configure/force also "milter-greylist" to block the
messagge (milter-reject) at the "postfix/cleanup" stage via postfix
configuration?
All others milter I've tried block the message at "cleanup" level,
all excpect milter-greylist.
Thanks
This is a function of the milter, not postfix. The general idea is
that the milter will block the message as soon as possible --
spamass-milter needs to see the whole message, whereas greylisting
only requires seeing the envelope data.
Ok, I understand.
Anyway, I don't see value in greylisting authenticated mail. All
this will ever do is annoy your users.
I'm using milter-greylist only for his rate-limit function.
Thanks
