maillog problems?

where are these coming from

[adwhite]

Hi,

I've been checking my maillog and I'm getting a load of entries that shouldn't be there. Like :-

Jun 28 22:58:05 ns sendmail[32473]: j5P4Kna26176: to=[e-mail], ctladdr=httpd (15/11), delay=3+17:37:16, xdelay=00:00:01, mailer=esmtp, pri=8047531, relay=example.net, [204.***.**.***], dsn=4.0.0, stat=Deferred: Connection refused by example.net.
Jun 28 22:58:05 ns sendmail[32473]: j5P4Gw325127: to=[e-mail], ctladdr=httpd (15/11), delay=3+17:41:07, xdelay=00:00:00, mailer=esmtp, pri=8047532, relay=example.com. [66.***.***.**], dsn=4.0.0, stat=Deferred: Connection refused by example.com.

There is no "from" so how are these getting there and does anyone know how can I stop them?

Cheers

Andy

The 'From' will be on another line. Try grepping for "j5P4Kna26176" in the logfile.

Hi,

No there is no "from" at least not in the log for the last week.

It could be up to 3 days (or more) in the past, but it will be there. At some point the message was generated, and assigned a unique id: j5P4Kna26176 and j5P4Gw325127 for the ones you're looking at. That same id is then used every time the mail server tries to send the message until it gives up.
