Spamassasin blocking mail from local subnet?

[Chewie71]

I have a couple users who aren't able to send email for some reason. They get the error... 550: denied due to spam list.

Is there a way to tell spamassissin not to scan emails sent from internal clients?

I enabled smtp debugging and this is what my Scalix smtpd.log is showing.

Hello,

this is not Spamassassin blocking the mail but the local smtp relay. Please make sure your local network is listed in /var/opt/scalix/sys/smtpd.cfg like this:

RELAY ACCEPT 192.168.1.0/255.255.255.0

Cheers,

Sascha.
