    I built a mail-relay server behind a fire-wall and cant get it to relay mail back to internet.
    It bounces the email immediately if the receiving external server is down.

    I'm pretty sure these settings are correct.

    Email Routing
    - Domain =
    - Destination =
    Email relay recipient

    What am I missing?

    Nope, neither sender, relay or receiving are not blacklisted.

    Do you have this problem for all recipients, or just for certain ones (same domain?)?

    ISPConfig Alias Email Domain Not rejecting bad users

    I'm sorry if this is not in the right category:

    In ISPConfig, Postfix is mishandling Alias Email Domain messages when user portion of email address is misspelled.


    Alias Email Domain: A-domain -> B-domain

    User: userA (mailbox in B-domain).

    Send a message to userA@B-domain (gets to userA@B-domain)
    Send a message to userA@A-domain (gets to userA@B-domain)
    Send a message to userB@B-domain (gets rejected)

    Send a message to userB@A-domain (creates userB in the B-domain folder, but should be rejected because userB doesn't exist @B-domain. Over time I have tons of Maildir folders with mistyped users@alias-domains that have to be cleaned up..

    Will continue to find possible mail drop issues that might be breaking in the mail user verify through alias domains..

    Thank you
