Hi,

according to Davide, the long awaited in- and outbound filtering will be rewritten in 1.14. Here an extract from his original post. Keep in mind, that this is just a raw draft, how things could be implemented.

QUOTE

Right now filter selection is pretty weak and now that I'm doing the
inbound/outbound split is going to be even weaker. I was thinking about
nuking the "filters" directory and have two files :

filters.in.tab
filters.out.tab

The syntax of those files is :

"sender" "recipient" "cip" "sip" "command" ...

Where :

sender = Message sender ( MAIL FROM )
recipient = Message recipient ( RCPT TO )
cip = Client IP
sip = Server IP

Example :

"*@mydomain.com" "*" "0.0.0.0/0" "0.0.0.0/0" "/bin/nukeit.sh" ...
"hacker@*" "*@safedomain.com" " "208.129.208.32/27" "192.168.1.12/32" "/bin/nukeit.sh" ...

This great change will boost XMail's flexibility again!

On the contrary of what it was before, now all the matching entries of the
appropriate file will be executed.

Just put high priority filter ahead in the file.

Yes, if filter A run before filter B and filter A modifies the message,
filter B will see the new message.
