Subject: Mail flood from 202.46.160.18 (www-wlg.domainz.net.nz)
Just a heads up in case any other ISPs are seeing the same thing..
I've had to block inbound traffic from www-wlg.domainz.net.nz - the load
average on our primary MX was at a nice healthy 97 thanks to an extremely
large number of connections originating from this mail server.
Thankfully, we were dropping it all on the floor because the sender domain
doesn't exist (why not?):
ruleset=check_mail, arg1=<4Service(a)wlg-iis.domainz.net.nz>,
relay=www-wlg.domainz.net.nz [202.46.160.18], reject=501 5.1.8
<4Service(a)wlg-iis.domainz.net.nz>... Domain of sender address
4Service(a)wlg-iis.domainz.net.nz does not exist
Domainz, please investigate and explain. I suspect whatever caused this
will have left a large amount of mail queued on 202.46.160.18 waiting to
be sent on.
Regards,
