Hi All,

> dns_available yes

This is rather a difficult one - on a mail gateway, no DNS is going to
cause rather a lot of problems.  By setting this to yes it seems to save
3 DNS lookups on every message processed in a batch (I've just looked at
Dns.pm).

The only time this is going to be useful is if DNS is temporarily
unavailable and SA would automatically disable RBL checks rather than
timeout each lookup, but you've still got the initial 3 lookups to
timeout first and MailScanner might timeout SA before it finishes
anyway.

> bayes_file_mode 0770

Remove or comment out - this was for MailWatch and Exim/Postfix users
only.

> bayes_ignore_header X-YOURDOMAIN-COM-MailScanner
> bayes_ignore_header X-YOURDOMAIN-COM-MailScanner-SpamCheck
> bayes_ignore_header X-YOURDOMAIN-COM-MailScanner-SpamScore
> bayes_ignore_header X-YOURDOMAIN-COM-MailScanner-Information

These should stay but be commented-out with instructions.

It's a shame we can't automatically add these at run-time being as
MailScanner will have these settings in memory.

e.g. When SA loads add a bayes_ignore_header config item for each header
value in MailScanner.conf.

> envelope_sender_header X-MailScanner-From

Keep - this is required for SPF checks, again as above it's a shame we
can't do this a run-time.

Remove - this is old now.

> score           IE_VULN         100.0
> describe        IE_VULN         Internet Explorer vulnerability

Remove - old, and has caused FP's in the past.

My 2p.

Cheers,
Steve.
