Hello there.
Since last night my SMTP is being hammered by various connections from
spammers, trying to send messages to or through my server. Exim does a
wonderful job rejecting the spammers, but they're so many that they are
swamping the smtp server (max connections = 400) and not letting real
email get to the server.
Seems like exim stays forever on a connection just giving rejects for
the host and it eventualy eats all the connections. And that occurs from
various hosts, dsl, dial ups, strange servers.
I limited the max connections from IP to 3, but with no help/
What strategy/configuration I can use to prevent/combat that?
