Trusted sender list not always working

I am having an issue where my trusted senders list is not always working for example: andrea@gcp.ink is in my trusted senders list yet here are two emails from her today

[2014.11.05] 17:10:27 [173.203.187.121][25175863] cmd: MAIL FROM:<andrea@gcp.ink> SIZE=162033
[2014.11.05] 17:10:28 [173.203.187.121][25175863] rsp: 554 Sending address not accepted due to spam filter
[2014.11.05] 17:10:28 [173.203.187.121][25175863] Mail rejected due to SMTP Spam Blocking: HostKarma - NoBlacklist, SpamCannibal, UCEProtect Level 1

[2014.11.05] 17:12:58 [173.203.187.113][59050626] cmd: MAIL FROM:<andrea@gcp.ink> SIZE=162048
[2014.11.05] 17:12:59 [173.203.187.113][59050626] rsp: 250 OK <andrea@gcp.ink> Sender ok

All of the emails from that address were delivered today except the one. I have had this issue in the past. Any one have any ideas what might cause this?

Based on the logs you provided you have SMTP blocking enabled. Since this occurs at the SMTP level it is before trusted senders would be applied. The two spam check are SpamCannibal and UCEProtect Level 1 that are being triggered. You may need to adjust the weight of these two spam checks.

Thanks for the reply. I didn't realize that SMTP blocking took place before trusted senders is checked. I have adjusted my settings to remedy this situation.

This seems like something that should be changed to have the trusted senders always override everything.

I'm thinking this should be a feature request. How hard would it be for smartermail to check trusted senders first? it should be a lot quicker than the rbls and dns lookups that normally slow it down.

Agreed, my thought was trusted sender would put a stop to any kind of checking.

SMTP Checks are now ignored if the sender is on your trusted senders list. This will be in the next minor release for both SmartMail 12 and 13.

Am I reading this correctly? From now on if someone has citibank.com or paypal.com in trusted senders then a phishing email pretending to be from one of those domains will be delivered even if the sender's IP is on 5 DNS Blacklists that you normally check?
