    I got some emails suggesting I tighten up some things for from cpanel security.
    So I did but now smpt is not working in WHMCS.
    I have tried a few things but no good.
    And I deleted the orig email from my cpanel so can't remember what was done.

    Error in WHMCS hwne trying to send email is....

    Email Sending Failed - SMTP Error: Could not connect to SMTP host.

    Email Queue Processing Completed

    If I change to using php for email it sends fine

    Hello :)

    Check to see if "WHM Home » Security Center » SMTP Restrictions" is enabled and if so, see if disabling it resolves the issue.

    Thank you.
