Hello all,

Today I noticed the following entries in my SIMS log. SIMS is
actually only an outgoing server, and it has some router entries
which point to other addresses when mail is sent to this domain. The
only local addresses are "Postmaster", as well as "Macjordomo",
"cfcnews", "cfcnews-on" and "cfcnews-off".

Relay for clients only is checked. For 1 minute, authenticated IPs
are treated as client ones. Nothing blacklisted, No blacklist DNS
server. RBL server list is empty. Client hosts are
172.16.0.2-172.16.255.255.  All mails are sent via my provider's smtp
server (mail.solnet.ch). SIMS Version is 1.8b9d14.

07:46:24 2 SMTP-342([62.152.65.205]) {S.0000028647} received, 425 bytes
07:46:25 2 SYSTEM [S.0000028647] S.0000028647 1+0 From:[EMAIL PROTECTED]
07:46:26 2 SMTP-343(mail.solnet.ch) [S.0000028647] sent, 316 bytes
07:46:26 2 SYSTEM(SMTP) [S.0000028647] sent to (lanck.net)agroreklama

07:47:11 2 SMTP-341([62.152.65.205]) {S.0000028646} received, 425 bytes
07:47:11 2 SYSTEM [S.0000028646] S.0000028646 1+0 From:[EMAIL PROTECTED]
07:47:12 2 SMTP-344(mail.solnet.ch) [S.0000028646] sent, 316 bytes
07:47:12 2 SYSTEM(SMTP) [S.0000028646] sent to (lanck.net)agroreklama

This seems that somebody pretending to be [EMAIL PROTECTED]
managed to send two messages to an address outside, at
[EMAIL PROTECTED] - but why was this possible?

And: The offender was at 62.152.65.205 - which, per the traceroute
utility, resolves to lanck.net as well:

Any ideas?

Thank you, Christian.
