Users cannot cc: others in same domain

[rusty]

Hi,

Since upgrading from ZCS 6.0.5 to 7.0.4, I have users complaining that they cc someone on an email who is on the same domain, and that user never receives it. Whitelisting the domain in each users GUI Preferences resolves it but I need a more global way to address this.

Does anyone have any ideas?

I noticed in amavisd.conf there is a new line that wasn't there in prior versions. Could this be the reason for this new issue? Should I comment this out?

@mynetworks = qw( %%zimbraMtaMyNetworks%% );

I have whitelisted the domains as per Improving Anti-spam system - Zimbra :: Wiki (Postfix whitelist when using RBL's) with no success. I whitelisted the domains in amavisd.conf and salocal.cf but that hasn't worked either.

Please correct me if I'm wrong, but this is the solution that I came up with. I didn't want to disable the spam filtering but instead exempt certain domains from being filtered.

In the /opt/zimbra/conf/amavisd.conf.in file under the $policy_bank{'MYNETS'} section I added:

bypass_spam_checks_maps => [[qw( .example.com .example.net )]],

To make the changes take effect, as the zimbra user run the following command:

zmmtactl restart && zmamavisdctl restart
