[tpop3d-discuss] Maildir locking, to prevent more than 1 simultaneous access?

[Rich, WhidbeyNet NOC]

Dear list,

I'm happy to say we've been running tpop3d 1.4.2 crash-free for over 2
weeks now, using auth-passwd. However today a customer uncovered a minor
problem.

When two or more clients access the same Maildir at once, tpop3d allows
all of them in. They can all get a LIST, and they all begin retrieving
and deleting mail.

Whichever client QUITs first will leave the other sessions in limbo. The
other clients will try to "RETR MSGNUMBER", and tpop3d will say "+OK
Message follows:". But because the message has either been moved to
"cur", or deleted, tpop3d just sits there, and eventually either the
client or tpop3d times out.
