Sendmail, a lot of mails stuck in /var/spool/mqueue

[Zairus Andersen]

Hi,

OS: Linux 2.6.5
tmpfs mounted at /var/spool/MailScanner/incoming

I'm having problems with sendmail (8.12.11), MailScanner (4.30.3) and
SpamAssassin (2.63). A lot of mails (not all) are geting stuck in
/var/spool/mqueue directory. Sendmail receives the mails and then it queue
them normally, MailScanner processes that but Delivery was not attempted and
it store the mails in /var/spool/mqueue. The mails that are not stuck in the
queue are correctly delivered.

We can see in the qf file that the delivery was not attempted:
V6
T1084868723
K0
N0
P1137115
Fbs

Mail log:
May 18 10:26:57 hl03 sendmail[21214]: i4I8PF7r021214:
from=<yyyyyy at yyyyyyy.com>, size=1107115, class=0, nrcpts=1,
msgid=<BCCF94C0.2AE9%yyyyyy at yyyyyyy.com>, proto=ESMTP, daemon=MTA,
relay=206.Red-80-39-234.pooles.rima-tde.net [80.39.234.206]
May 18 10:27:12 hl03 sendmail[21214]: i4I8PF7r021214:
to=<xxxxx at xxxxxxx.com>, delay=00:01:49, mailer=esmtp, pri=1137115, stat=queued

As you can see, there's no delivery attempt in the log file and if I run
queue manually (sendmail -v -q) message i4I8PF7r021214 is not processed.

Mailq entry:
i4I8PF7r021214X 1106688 Tue May 18 10:25 <grafico at graficogabinete.com>

Message appears to be queued because server's childrens go up to the
MaxDaemonChildren,  I have deactivated sendmail's load check
(LA_TYPE=LA_ZERO). In the queue runs this message never is attempted.


OS: Linux 2.6.5

Any idea about this problem?
