What is this "imapd: port 2368 service init"?

[Hugo van Galen <hugo () TLOGICS NL>]

Hi everyone,

We have been getting this kind of messages in the debug-log of a
Slackware 7.1 system. The system is behind our firewall, and only
non-privileged ports up to 4999 are allowed to pass through.

We had this message once, a few weeks ago, but this weekend we have been
getting more.

Can anyone tell me what's with this port 2368, perhaps that anyone has
seen this before?

Thanks in advance for any help,
