Hi all,
Recently seen a spurt in spam going out from my server.
What I have seen is that in such cases, this is the log.
CHKUSER relaying rcpt: from <xx...@sail-steel.com:rmfpwr:> remote
<k.st:unknown:183.5.232.68> rcpt <yangjuan...@qq.com> : client allowed
to relay
Now, in my tcp.smtp, this client is not allowed to relay. So am stumped
as to how this client is allowed to relay ? A small investigation showed
up that the To address in such mails is coming as below :
simscan:[5907]:RELAYCLIENT:1.8346s:-:183.5.232.68:xx...@sail-steel.com:905690...@qq.com,1047623...@qq.com,z...@job20.com,285090...@qq.com,cq445_...@qq.com,huajing-2...@qq.com,4559...@qq.com
There is a : in the to line. Is that causing the problem ?
My server is accepting this, trying to deliver, failing, and bouncing to
users in my domain ...
Thanx
Anand
