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.
Escape character is '^]'.

It suggests to be a resolving issue. But I haven't changed anything else
except for databytes.
