I've lost the original message, this is a copy and paste from the archive.
For a refreshing of the mind I included the complete original message below.

Since we've experienced a major outbreak of virusses at the company I work for and
ppl are allowed to send smtp to other hosts (company rule, it's stupid I know) I
was forced to try this, because we would get cut off by or provider if I had no
quick fix.

I can say it works !
Maybe this is also possible for the transparent proxy thingy ppl ask for so often !

Met vriendelijke groet,
Jeroen Visser.
Sure, we know Unix, we've seen it in Jurassic Park...

It surely would piss me off to and would hate it if my ISP would do that
but indeed its for the clueless users who don't know how to change there
settings... :(

My clients are located on LAN, SMTP server is located on WAN

Will the rules be something like this then?

Agreed and it'd piss me off for sure, but I understand the necessity
of it for 99.9% of clueless users out there.

I recall something in the archives about somebody doing something
similar using a hacked NAT rule.

Like manually put something like this in your config.xml backup and
restore it.

  <descr>redirect SMTP to LAN SMTP server</descr>

where is your SMTP server.

That might really screw stuff up though, so test it thoroughly first
to make sure it has no unintended consequences (if it works at all).

If someone tries it, please let me know if it works.
