Since 2 weeks I have many files staying in mqueue-rx (dual sendmail)

Again I am using dual sendmail with amavis and
spamassassin and DCC, Pyzor, Razor.

Since two weeks I get many files in sendmail-
receiving spool area (Files: d* and q*).

When this happens for the first time (mostly
on a weekend) then mail processing will be stopped
and not continued. There are about 300 files
in mqueue-rx (d* and q*).

Afterwards many files (about 70) will be
created in transmiting "mqueue" for the
second sendmail-process.

The machine has 512 MB Ram and 170 MB free
of main (not swapped) space at this time.

What can be the Reasons ? What to analyse ? What more
information do you need to help me ? What can I do ?

Thanks Harald

Re: Since 2 weeks I have many files staying in mqueue-rx (dual sendmail)

My configuration of versions:

I am using SuSE V10.2, dual-sendmail (sendmail-8.14.0),
amavis (amavisd-new-2.4.3 (20060930), clamav (0.91.2/4659/Thu),
spamassassin (3.1.8), dcc (dcc-dccd-1.3.42),
razor (2.82, prot V3), pyzor (pyzor-0.4.0), perl (5.8.7).

sendmail (rx, mqueue-rx) will receive any mail on port 25
sendmail will send the mail to amavis
amavis will do on port 10024:
- clamav should scan each mail or viruses
- spamassassin should scan for spam
- DCC, RAZOR, PYZOR
There are three file lists (/var/spool/amavis):
- spam_lovers
- whitelist_sender
- blacklist_sender
- spam will be marked as spam and should go through
- sendmail (tx, mqueue) will receive message on port 10025
and should send mail by virtusertable to sender

Thanks Harald
