Cached Timeout MailScanner

Wed May 27 13:56:02 IST 2009

In recent experience on my systems, this was due to an increase in the size of some spam. I also believe it was related to an increase in the number of rules I have enabled recently. I checked the size of the emails that were involved in the timeouts and they were generally larger than 50kbytes. There are many potential causes however and anything that can cause SA to run longer than the timeout in MailScanner.conf can generate these. Ultimately I increased my timeout value.

SpamAssassin Timeout =

I believe the "failure x of 20" is saying that soon (if the count reaches 20) MailScanner will disable SA checks and pass emails unscanned. This is to prevent SA failures from causing a full mail stoppage.

		Depends on the amount of of traffic and size of the emails, but that should be good enough for a a few 100k of emails per day.
