--max-children setting, consider raising it
There is a problem. You're overloaded. I don't know if spamd being
overloaded would result in spamc reporting interrupted system calls, but
that would explain the behaviour you are seeing:
The problem is that spam works a few minutes then let it pass all
messages giving a score of 0.00 in the log
From the spamc man page:
-t timeout, --timeout=timeout
Set the timeout for spamc-to-spamd communications (default: 600, 0
disables). If spamd takes longer than this many seconds to reply to
a message, spamc will abort the connection and treat this as a
failure to connect; in other words the message will be returned
unprocessed.
"unprocessed" == "score of zero".
You might try using spamc's "-x" option, which will tell qmail that spamd
is overloaded rather than skipping the scan. I don't know how simscan will
respond, but it's likely the messages would be queued for retry. Messages
would take longer to be delivered, but they would all be scanned.
you said we have 3 mx with each SA, which work well only 2 and 3 is
where the error comes, If influence on our server reaches around 75,000
emails received daily.
You may want to add memory and increase the number of child processes.
Are you using any DNSBLs to reduce load within qmail at SMTP time, before
the messages get passed off to SA for scoring?
