Hello,
My sendmail daemon is frozen every now and then. The only extrange thing I
found on the logs (/var/log/maillog and /var/log/messages) is this:
> Feb 6 18:24:43 www sendmail[445]: SAA00445: from=<[EMAIL PROTECTED]>,
> size=2660, class=0, pri=62660, nrcpts=2, msgid=
> <00001b3a3abe$000006cc$[EMAIL PROTECTED]>, proto=ESMTP,
> relay=ns.escada.co.jp [210.162.109.146]
> Feb 6 18:25:11 www sendmail[447]: SAA00447: to=<[EMAIL PROTECTED]>,

> lay=mx2.777.net.cn. [202.98.123.85], stat=Deferred: Connection reset by
> mx2.777.net.cn.
and a lot of this "Deferred" messages... The message is still on the queue
of sendmail. Is this a sympthom of an known attack? I could easily delete
this message from the queue, but I want to be sure of not being attacked!
Thanks,
Tomas Garcia Ferrari
