Good afternoon,
I take a look each week at senderbase to check and see what others think
my network is sending out in terms of mail volume. I generally find it
helpful.

Anyone else using that report? I ask because I have two IPs showing up
there as having excessively high mail volumes, yet the IPs they list
have port 25 blocked at the client router.
Are you sure? And bear in mind, you need to be considering outbound access, not
inbound.
Yes, we blocked them at their Cisco because they had been compromised
(Motel with free internet access). Blocked in and out and forced the sue
fo webmail and smtp-auth.

ie:
<your ip>:<anyport> to <anyip>:25
not:
<anyip>:<anyport> to <your ip>:25
You might try logging into a box with one of those IPs and trying to telnet to
an outside mailserver. (you can use xanadu.evi-inc.com for this if you wish, but
do be nice and merely issue a quit command if you connect.)
telnet xanadu.evi-inc.com 25
220 xanadu.evi-inc.com ESMTP Unsolicited Commercial Email prohibited
quit
221 2.0.0 xanadu.evi-inc.com closing connection
Connection closed by foreign host.
I have send two emails to [EMAIL PROTECTED] and received no replys
so far. Am I spinning my wheels here?
