MCP-Checker (MCP timed out) - what is happening?

[Quentin Campbell]

Jeremy

Have run 'spamassassin --siteconfigpath=/etc/MailScanner/mcp --lint' and
this shows no problems. In my case I have more than one *.cf file in
~/mcp.

I have found 59 instances of this problem occurring over the last 8
weeks. That is a tiny number compared to the 1,000,000 or so messages we
receive per day so the problem seems to arise out of a very special set
of circumstances.

Not just mail from 'intl.pepsico.com' is involved although that site
accounts for a significant proportion of the 59 cases. At least two
different people sending mail from that site have beem affected.

A full extract of log records for one such instance is:

Jun  1 10:12:26 cheviot2 sendmail[25995]: k519CLJN025995:
from=<xxx.yyy at intl.pepsico.com>, size=2953, class=0, nrcpts=1,

Jun  1 10:12:39 cheviot2 MailScanner[22318]: Message k519CLJN025995 from
195.33.104.10 (xxx.yyy at intl.pepsico.com) to newcastle.ac.uk is MCP,
MCP-Checker (MCP timed out)

Jun  1 10:12:39 cheviot2 MailScanner[22318]: MCP Actions: message
k519CLJN025995 actions are deliver

At this point the message disappears from the queue. It is not delivered
and the log records above confirm this.

I am running with MailScanner-4.51.6-1 and SpamAssassin 3.1.1.
