Hello all,

Can I have for SFI in my AllowedDomains.txt
particulardomain.com:IP.ADDRESS.FOR.RELAY
*

this way, I can filter and relay mails for a particular domain while using the standard settings for the rest of the domains.

thanks in advance.

Atif,

I'm sorry, you lost me here :-) maybe it's the wildcard in there...

So let me try explaining how that list works.

In the AllowedDomains.txt file you can specify, for any domain in that list, an optional destination SMTP server (and an optional port) where to forward emails addressed to that domain. If a domain has the optional destination SMTP server, that's where the emails will be forwarded. If there is not an optional dest. server, the emails will be forwarded to your default destination SMTP server in SpamFilter.

So if you have in the list:

atif.com
roberto.com
particulardomain.com:192.168.1.1
particulardomain2.com:192.168.1.2:26

emails to atif.com and roberto.com will be delivered to your "regular" destination SMTP server.
The ones to particulardomain.com will be forwared to port 25 on 192.168.1.1.
The ones to particulardomain2.com will be forwared to port 26 on 192.168.1.2.

Was this the question...?

The wildcard will be a problem, as that will cause SpamFilter to accept emails for every single domain, and thus will cause SpamFilter to become an open relay.
You will have to prevent that from happening, either by using an "AuthorizedTO" whitelist to define the allowed users, or by limiting the acces by IP (which is not practical if the server is receiving emails from the internet).
