SA-Exim - not scanning local nets.

[Simon Avery <we...@mareandfoal.org>]

Hi

Sorry if this is a FAQ but I've been playing the google game for hours 
now and still haven't got it right.

I have SA-Exim running and I want it to ignore any mail coming from 
local domains (ie, a 10.0.0/24 etc) because the users within these nets 
are complaining the sending delay is too big.

I've tried following half a dozen rough guides, which assume a lot of 
knowledge of Exim by restricting by ACL, but they don't work for me. 
I've also been advised to use trusted_networks in SA's local.cf but 
again, that adds a flag but doesn't stop it scanning and creating this 
rather large delay. (5-15 seconds)

Can anyone please point me to the right way of doing this that is proven 
to work? Spent /way/ too much time chasing this one around and around.

Thanks.

Simon

You could leave SA-Exim and use spamassassin in your maildroprc (if using maildrop) or maybe in mailproc.

That way SpamAssassin would activate only for incoming messages, and outgoing transfer would be speedy.

maildrop is good.

Why don't they work for you? The setting controlling whether SA-Exim contacts 
spamd or not is SAEximRunCond in /etc/exim4/sa-exim.conf. Since SA-Exim's 
configuration parser is very simple and doesn't allow line continuations, the 
condition can become rather unwieldy. For that reason, I recommend setting an 
ACL variable in Exim's ACLs. You should find an example in sa-exim.conf, or 
in sa-exim.conf.dpkg-dist if you have upgraded and opted to keep your own 
version of the configuration file.
