Some mails in outgoing queue don't get processed

[Knutzen, Heinz (DZ-SH)]

Hi,

since yesterday I have trouble with my sendmail/mailscanner setup:
Some mails remain in /var/spool/mqueue and don't get processed.
There are thousands of mails which get processed ok,
but I have about 70 mails with dates from yesterday to now
which stay in /var/spool/mqueue all the time.

When doing 'mailq', all 70 mails are shown.
But if I do a 'sendmail -v -q', only 1 or two recent mails are processed.
All of these qfiles have lines like

qfh0N1Ohvm007970:MDeferred: Connection refused by [10.48.242.10]
qfh0N6Okvm012640:MDeferred: Connection timed out with [10.107.64.10]

but currently there are now connection problems.
Restarting sendmail and removing /var/spool/mqueue/.hoststat/ 
doesn't help either.

Any ideas, how to get them delivered?

Version info:
mailscanner-4.05-3
sendmail-8.12.2-88

Viele Grüße
