The "mqueue" directory is the "outgoing" directory as per MailScanners
point of view, which means that the reason for specific mails to be
held up there would be solely a sendmail problem, not MailScanner as
such.I suspect that you would see the reason if you traced one of the
"offenders" in your logs, or that the mailq command may show it...
Most cases it'd probably be the destination MTA returning a 4xx code
(temporary failure, try again later).
The mqueue.in" catalog problem messages would be more of a MailScanner
thing... the queue files will suiit there until MailScanner is done
with 'em, so a very long pause here may indicate a problem. What does
"MailScanner --lint" show you? If you run "MailScanner --debug" (with
only a problem message in the queue), what does that tell you?
Apart from that, it's impossible to say more without log info (a clear
trail of one message, perhaps with a little chunk of extra lines
