The run script is in /var/qmail/supervise/pop3d/run.
The script is exactly as shown in djb's pop3d directions.
exec tcpserver -v -R 0 pop3 /var/qmail/bin/qmail-popup host.domain.com \
bin/checkpassword /var/qmail/bin/qmail-pop3d Maildir 2>&1 | \

It doesn't hang with telnet.
The mail clients (Outlook in this case) are able to connect to the pop3 and
authenticate, but not retrieve mail messages. A tail --follow=name maillog
gives shows this as the reason for the timeouts:

This is a really low volume server. There are rarely ever more than about 4
simultaneous connections.

I changed the actual addresses to protect the innocent. :)
