<div>Hi all dovecot
members,</div><div><br></div><div>I've
received this notice from a dovecot server: <span style="font-size:
12.8px;">
"Stale mailbox lock file detected, will override in 0
seconds"</span></div>
<div><span style="font-size:
12.8px;"><br></span></div><div>I would like to
know what it means.</div>
<div><br></div><div>I've implemented a "Mail
Proxy Server" in java, which connects to many accounts and folders,
listening for incoming messages or deleted one, it uses the IMAP
protocol.</div>
<div>I received that message only 5 times in 60 days of logs, last time,
in the same time lapse my server has not received three messages, saying
differently, the listener (I'm using Javamail which works fine) has not be
notified about those new threee messages.</div>
<div><br></div><div>So, I would like to find a link
between the above dovecot message and the "black-out" which I had,
could you help me please?</div>
<div><br></div><div>Thanks,
bye</div><div><br>Raffaele Gambelli<br>WebRainbow®
