Hi all,

I have been wrestling with my servers trying to cut down on the amount of spam we are sending.

Can someone translate these log lines:

2008-03-16 18:36:06 1Jb1SX-000Eu2-Ll <= <> R=1Jb1SV-000Etp-55 U=mailnull P=local S=1185
...
2008-03-16 18:36:14 1Jb1SX-000Eu2-Ll ** binod@??? R=dnslookup T=remote_smtp: SMTP error from remote mail server after RCPT TO:<binod@???>: host borland-mxa.mail.eds.net [192.85.154.83]: 550 5.1.2 <binod@???>... Rejected: 69.90.69.141 Backscatter
2008-03-16 18:36:14 1Jb1SX-000Eu2-Ll binod@???: error ignored
2008-03-16 18:36:14 1Jb1SX-000Eu2-Ll Completed

it looks to me as if the original message was rejected because the remote mail host seen my server as a spammer.

What I need to know, is how did the original message (log line 1) get into my server at all? How can I beef up the loggin to tell me if it was a localy generated message, or if Ihave a hacked account. (password 'guessed').?

The original message was generated systematically - it's a bounce.

UÚilnull P/cal S?85

The "R@part shows the Exim message ID which caused the bounce. Grep
that out of your logs to see what caused it.

I'll punt one probably cause: you're not doing SMTP time rejection, but
are accepting and bouncing for invalid recipients.
