Anyone built a smtp proxy like plugin? I've been using qpsmtpd on my
qmail installations with great success, but now I need to handle a
postfix installation. queue-postfix works, but it leaves me with no
rcpt checking. I could do it with a hand edited list using the
aliases_check plugin or just a simple for loop on a flat file but the
other admins are a little too lazy to edit a file each time they add a
user or alias.
A better solution would be a plugin that could connect to another smtp
server, and do the first parts of the smtp transaction up to the RCPT.
If the other server rejects then qpsmtpd should reject.
A further enhancement would be to hook the queue portion as well and
pass the entire message along, giving qpsmtpd the ability to serve as a
proxy for Exchange or other servers.
I can probably write something, but I hate to do the work if someone
already has something lying around.
Thoughts?
Thanks
