Some email not coming through w/ Greylisting
I am a web designer and I provide hosting for a few dozen clients.
I am new to Greylisting in WHM.
I noticed yesterday an email is stuck in Greylisting for 17 hours. I checked in mail reports and see this:
I've read somewhere that some senders use multiple IPs, making a problem for Greylisting, and I wonder if this is such a case. Or maybe that address US Govt / Medicare doesn't resend? I know I can add that IP to Trusted Hosts, but I am wondering why it's not coming through. I have an initial delay of 5 min and then 240 min Resend Acceptance Period and then a 30-day Record Expiration Time. I'd appreciate anyone's helpful input! :)
Deferred due to greylisting. Host: '173.226.xxx.xx' From: 'mymedicareadmin@cms.example.gov' To: 'address]' SPF: 'unchecked'

Hello, You can search /var/log/exim_mainlog to see if the sender attempted to resend the message with a command such as: exigrep sender@domain /var/log/exim_mainlog
More information on Greylisting is documented at: Greylisting - Documentation - cPanel Documentation Thank you.0
