Mailserver reports two login/logouts

[Frank Schruefer <frank@siteforum.com>]

Hy,


Im checking mail with javamail 1.4.2 on a pop3 mailserver.
The mailserver logs say that two logins/logouts are made:

Oct 14 17:02:32 sfmail01 pop3d: Connection, ip=[::ffff:91.66.207.201]
Oct 14 17:02:32 sfmail01 pop3d: LOGIN, user=webmail.demo@siteforum.com, 
ip=[::ffff:91.66.207.201]
Oct 14 17:02:32 sfmail01 pop3d: LOGOUT, user=webmail.demo@siteforum.com, 
ip=[::ffff:91.66.207.201], top=0, retr=0, rcvd=18, sent=49, time=0
Oct 14 17:02:32 sfmail01 pop3d: Connection, ip=[::ffff:91.66.207.201]
Oct 14 17:02:32 sfmail01 pop3d: LOGIN, user=webmail.demo@siteforum.com, 
ip=[::ffff:91.66.207.201]
Oct 14 17:02:32 sfmail01 pop3d: LOGOUT, user=webmail.demo@siteforum.com, 
ip=[::ffff:91.66.207.201], top=0, retr=0, rcvd=6, sent=30, time=0


while the connectionlistener only reports two logins/logouts (Printed the 
Events to System.err):

javax.mail.event.ConnectionEvent[source=pop3://helpdesk.demo%40siteforum.com@mail.siteforum.com]:
 opened.
javax.mail.event.ConnectionEvent[source=pop3://helpdesk.demo%40siteforum.com@mail.siteforum.com]:
 closed.


Any idea why there's a second login/logout happening or how I can debug this 
further?

If I'm using another mailclient the server reports one login/logout as 
expected,
So it shouldn't be a problem on the mailserver side.
