Hi all,
I have been working on removing qmail from one of our larger systems in
favor of exim and I've hit two little gotchas, I wonder if these ideas
could be included in a future exim..
1) Abusive SMTP input
Our list server runs qmail and as we all know it fires off one connect
per recpient. This new exim server has many people subscribed to the
various lists so qmail hammers it very hard. Exim neatly limits to 20
connections, but instead of just delaying new connects and letting them
sit on the listen queue (like tcpserver does) exim fires back a '4xx too
many concurrent users' response. This seems less than ideal. I would
like to see an option for tcpserver-like behavior
2) Weird .forward stuff
Most of the things I was to deal with in a fairly sane manner, but
two stood out..
a)
cat .qmail-default
|forward foo-$EXT@???
b)
cat .qmail
./MailDir/
a is probably impossible without procmail or an exim filter or
something, still, it is a rather interesting idea.
b+c strike me as legtimately usefull './' should indicate a file/directory
and expand to $HOME.
Thanks,
Jason
