    Hi all.

    I'm not a good programmer (except in PHP) so I can't just find the answer in the source of cPanel.

    I would love to enable the "check for email existence before accepting email" option in Exim configuration; however, when I do this, some (well, a lot) of emails get blocked. Some should get through, but yet they're blocked.

    For example, a vB forum I subscribe to won't "answer" the question when Exim asks, and so the subscription emails will be lost / trashed because there's no authoritative answer for the user sending the emails (even though the account exists).

    I'm trying to get to the bottom of the issue. Whether it's an implementation of how the script checks for validity, or whether some email servers aren't following an RFC or if it's a feature that's just turned off.

    Thanks for any insight you can give me.
