local mail getting marked as spam?

[quote user="13425Elon"]Did anyone solve this?[/QUOTE]Did you read some of the suggestions in this thread?
[quote user="13425Elon"]TVD_RCVD_SINGLE is annoying.[/QUOTE]The score for that test is not likely to cause any great problems. Posting comments like that without any information on what exactly your problem is and no information on which version and release of Zimbra is in use doesn't actually provide anyone with enough information to offer you any advice.

local mail getting marked as spam?

I had the same problem as ewilen (post 50).

Emails sent from VZW-Verizon Wireless (Android phones in my case) was being Junked because of the following two rules: HELO_ALMOST_IP=3.565 and HELO_DYNAMIC_SPLIT_IP=3.493

My work around was to lower the score for anything originating from VZW by adding the following to /opt/zimbra/conf/salocal.cf.in :

# rule to allow emails from Droid phones through spam filter.  The Droid email originates

# from VZW IP addresses.

header LOCAL_RULE_VZW_1 Received =~ /[70.(19[2-9]|22[0-3]|2[0-1][0-9]).d{1,3}.d{1,3}]/

describe LOCAL_RULE_VZW_1 passed through Verizon Wireless

score LOCAL_RULE_VZW_1 -6.5
Since Verizon wireless owns 70.192.x.x - 70.223.x.x, this lowers the spam score of anything originating in that IP range by -6.5. That's enough to get it past the spam trap. This is far from optimal because it would also let email from actual spammers on VZW through, but so far that hasn't been a problem for me.
This might work for someone else if the users who send from an external network can be pinned down to at least a small number of specific IP ranges or subnets.
