[imp] POP3 woes

Hi, listfolk.

I'm setting up IMP to talk with our customer mail system at work which, 
admittedly, is a bit old for which I cannot get IMAP support (or even 
updates for that matter).  I did some sniffing with tcpdump on the 
mailserver and noticed that the sessions are ending properly during 
first login, but I'm getting error messages saying that the mailbox in 
question is locked and in use by another session even though, 
protocol-wise, the most recent session had been ended.  However, I 
suspect that the POP3 server process isn't terminating quickly enough to 
service any subsequent requests.  As a result, IMP periodically works 
and doesn't.

Is there any way short of hacking the source itself to insert a delay 
after logoff so in case IMP needs to log in again right after closing a 
session, it can get something?  Yes, I realize these could add up really 
quickly, but for right now, this machine is all we have.  Otherwise, I'd 
be all over an IMAP server in a tick-tock.

FWIW, this is a Post.Office installation IMP's connecting to whose 
mailboxes are reminiscent of Maildir, yet not.

Thanks!

--Ian.
