I offer Enterprise-grade anti-spam and anti-virus software for Linux
that may be a more effective solution for you.  It can run either on
a Linux mail server or a Linux Firewall.  If running on a Firewall,
it does not matter what platform the mail servers behind the Firewall
are.

&gt; fetchmail --antispam 451

&gt; However, the log tells me this:

&gt;  *** snip ***
&gt;  reading message dsj%dsj.net at pop.dsj.net:28 of 28 (5284 octets)
&gt;  fetchmail: SMTP error: 451 4.1.8 Domain of sender address
&gt;  rainer at augsburg.net does not resolve
&gt;  ..... not flushed

&gt; Why doesn't fetchmail believe me?  Why doesn't this message get
&gt; flushed as I asked it to be?  All help welcome.  TIA!
