What???
Last I heard, WebShield SMTP is a virus scanner. It is VERY spam friendly
-- in fact, I still haven't gotten confirmation that any version will
record the IP address of spammers! That's one of the most important things
to record in a Received: header, and without it, no spam control program
will be able to use any of the 50+ DNS-based spam databases that use the IP
address of the sender of the spam. That's very, very bad.
For example, the Received: headers on your E-mail were:
Received: from list.ipswitch.com [156.21.1.21] by declude.com with
ESMTP
(SMTPD32-7.06) id A89841830452; Mon, 24 Jun 2002 11:19:52
-0400
Received: from email.collectron-int.com [148.235.4.107] by
list.ipswitch.com with ESMTP
(SMTPD32-7.10) id AB5E922A00BC; Mon, 24 Jun 2002 11:31:42
-0400
Received: from email.collectron-int.com [192.168.1.2] by
email.collectron-int.com
(SMTPD32-6.06) id A762C90432; Mon, 24 Jun 2002 08:14:42 -0700
Received: FROM winnt2000 BY email.collectron-int.com ; Mon Jun 24
08:14:38 2002 -0700
Notice that the last Received: header -- the one that WebShield added --
hid your IP address, and only included the "winnt2000" HELO/EHLO text that
your mail client sent as identification. As I'm sure you know, there is no
way to tell who "winnt2000" is -- it is not a fully qualified host name,
and is not valid (the same way that most spammers out there
operate). That's acceptable for WebShield to do on outgoing mail, to hide
your IP (since your WebShield SMTP is set up so that it can only be
accessed by authorized users, unlike most WebShield setups). However, for
incoming E-mail, you won't have any idea where the E-mail came by looking
at the E-mail headers.
WebShield certainly does a decent job scanning for viruses (I hear that
they have now fixed the DoS issue I reported to them a couple years back
fixed), but it is lousy for spam control (you'll have better spam control
by uninstalling WebShield).
