RE: Qmail SMTP timing out.
I had a similar problem. Without going into the details, mine was caused by the proxy dropping the connection. Have you tried snoop to watch the packets spray to test for errors with netstat?

Server is most likely unable to do a reverse DNS lookup on those clients. Jon On Wed, 27 Jun 2001, Grant wrote: Qmail has been working perfectly up until yesterday. What I did was: echo 10485760 /var/qmail/control/databytes and restarted qmail. While this is nothing major, ever since yesterday _some_ clients have been reporting timeouts on sending emails. I telnet from the clients machine to port 25 of the mail server and I get nothing. Whereas if I telnet locally to port 25 I get: Trying 127.0.0.1... Connected to localhost.localdomain.

But I haven't changed anything else except for databytes.
Re: Qmail SMTP timing out.
How can I tell it not to reverse lookup 192.168.* I don't know why it has just started doing this. Obviously someone has changed something I'm not aware of.
