http runs through a proxy server, so I would get a different public IP than SMTP sessions use to reach the mail server. Not that I would have any significant filter logic rely on a service whose format, existence, and reachability could change at any time. There's so much to set up on a new server, that I have a hard time seeing the benefit of jumping through a lot of hoops to have the same filter run unmodified on several at once. I suppose that if you wanted to push out changes to a cluster of mimedefang boxes and have some filter logic that knows your own IP, then put it in /etc/mail/mimedefang-filter-local, and source it as a library. > What I think would be really nice is a new kind of DNS > record... something like WHOAMI... that provides this kind of > a service.

NAT aside, it would be nice to know sometimes - even on a multi-homed server which address was used for a particular connection. I don't necessarily agree that DNS is the place to fit this, but it's an idea that's worth developing. _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
