DNS. That's classic DNS problem symptioms. The various servers are performing a reverse lookup to log the entries by name - and you are waiting on the DNS timeout. I bet you'll find the logs for both mail and SSH are full of IPs, with very few names.
<br />
<br />Check your DNS settings to be sure you have a valid/good DNS server listed as first in the /etc/resolv.conf file. You can modify that file by hand or via the GUI in the system settings.

Subject: [BlueOnyx:06825] slow Sendmail response
<br />
<br />> After migrating from a low powered BQ box to an overpowered BO box, my
users have reported that Sendmail is incredibly slow to respond. They noted that
emails sit in their outlook outbox for quite a while before transferring over.
<o:p />
<br />> <o:p> </o:p>
<br />> I also noticed that if I telnet to
port 25, it connects instantly, but it’s a good 10 seconds before I am
greeted with a banner. <o:p />
<br />> Connecting via SSH also exhibits a
10+ second lag before it tries to log in. <o:p />
<br />> Connecting via the
GUI is instantaneous. <o:p />
<br />> <o:p> </o:p>
<br />> The server
is sitting almost idle and is barely working at all (99%id, all others sitting
at <0.5%). <o:p />
<br />> <o:p> </o:p>
<br />> Any ideas on what to
check first? <o:p />
