Hi
I have probably trivial problem - but I cannot resolv
I have two server
1)for outgoing
2)for incoming (typical mx)
For test i create in (incoming server) body_checks.pcre:
/alakot/ REJECT spam2bok bla bla
If i send e-mail from external (gmail, yahoo) I get info from
Mailer-Daemon about REJECT - works fine
but if i send from my domain I dont get Mailer-Daemon:
May 16 12:08:38 MX-node1 postfix/cleanup[45210]: 4L1w1y6WBVz1DDmK:
reject: body alakot from smtp....[xxx.xxx.xxx.xxx];
from=<[email protected]> to=<[email protected]> proto=ESMTP
helo=<smtp.domain.ltd>: 5.7.1 spam2bok bla bla
May 16 12:08:39 Mx1-node1 postfix/cleanup[45282]: 4L1w1z0zmpz1DDmn:
reject: body alakot from smtp....[xxx.xxx.xxx.xxxx]; from=<>
to=<[email protected]> proto=ESMTP helo=<smtp.domain.ltd>: 5.7.1 spam2bok
bla bla
Is this correct beacuse body_check check "second time" when incoming return
Any idea to whitlist ?
You included no "postconf -n" settings, so I will wast some bandwidth
with random text.
