The VPOP3 settings show the first 100 messages in the LAN forwarding queue. Usually this is sufficient as the LAN forwarding queue is usually nearly empty, but in case of a problem it may be much bigger. The database queries below may help in that situation.

At a command prompt in the VPOP3 directory run

psql

(The password is 'vpop3pass')

Then, type

SELECT sender,target,subject,r.username || '@' || r.domain as recipient FROM messages.outgoing INNER JOIN messages.outgoingrecipients r USING(msgid) INNER JOIN messages.outgoingtargets USING(msgid) ORDER BY msgid;

to list all the messages in the LAN forwarding queue

or use

SELECT count(*) FROM messages.outgoing;

to simply get a count of the number of messages in the queue

N.B. VPOP3 does not need to be stopped while you do this
