RE: [Declude.JunkMail] Gateway and web server

 The ideal solution, however, would be to fix any problems 
 with the web 
 servers.  If the E-mail they send can get blocked by Declude 
 JunkMail, it 
 can get blocked on other mailservers as well.  So fixing the 
 problem rather 
 than using whitelisting is a better solution (although not as easy).

It looks to me like most webserver form submissions get caught by
Declude. By caught I mean that they get a weight more than 10. Seems
like they fail the valid mail client test and legit content.

What matters most is the specific tests they are failing.

An E-mail that fails the MAILFROM test is normally an illegitimate E-mail 
(I can't think of any good reason for an E-mail to be sent from an address 
on a domain that does not exist).  So that should be very easy to fix.

As for the NOLEGITCONTENT test, you can ignore that -- Declude JunkMail is 
designed so that legitimate mail failing the NOLEGITCONTENT test won't have 
its weight affected.  So an E-mail failing just the NOLEGITCONTENT test 
should never be considered spam.

[Declude.JunkMail] Gateway and web server

2003-11-02 Thread Jonas

We have 2 mail gateways and I have put their IP addresses in IPBYPASS
in global.cfg.

We also have some web servers on the same C block as the gateways so I
WHITELIST'd the whole C block because otherwise form submissions would
get blocked. Most of the web sites are assigned IP addresses which was
the reason to whitelist the whole C block.

I have a hunch that this is not the correct way of doing it.

That will work fine, as far as Declude JunkMail is concerned.  The IPBYPASS 
lines will cause Declude JunkMail not to see the IPs of your gateway 
servers, so the WHITELIST entry won't whitelist E-mail that comes from the 
gateway servers.

The ideal solution, however, would be to fix any problems with the web 
servers.  If the E-mail they send can get blocked by Declude JunkMail, it 
can get blocked on other mailservers as well.  So fixing the problem rather
