    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:
    Code:
    [I]Deferred due to greylisting. Host: '173.226.xxx.xx' From: 'mymedicareadmin@cms.example.gov' To: '[email address]' SPF: 'unchecked'[/I]
    
    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! :)

    Hello,

    You can search /var/log/exim_mainlog to see if the sender attempted to resend the message with a command such as:

    Code:
    exigrep sender@domain /var/log/exim_mainlog
    More information on Greylisting is documented at:

    Thank you.
