I am having massive problems with data timeouts lately under Debian.
Some Mailservers get an SMTP timeout.
for instance:
2003-10-03 04:12:43 SMTP data timeout (message abandoned) on connection
from extra.nordclick.de [62.214.54.90]
I habe fiddled around with ident/Port 113, because servers like this
seem to have a firewall which "eats" ident lookups and my server does
not get an answer, so he cuts connection. But with
"rfc1413_query_timeout = 0s" ... this should not be happening?
I have tested a connection to my server with telnet and it did not
timeout, even if I take my time...
So I am very confused. I suppose there is some kind of lookup that is
not functioning.
I have just switched Exim from Daemon to Inetd-Mode. But this did not
change anything.
