Bounced SMTP mail

joequick
V7.305 SMTP relay (no exchange server) Not using the user portal as prefetch has caused problems in the past.

No sure if this is related to another trouble ticket I have open with support or not (SMTP not filtering expressions).

Ok got that out of the way.
The mail manager is showing a few bounced emails.
The message is 553 sorry, your envelope recipient domain must exist (#5.7.1)

Which tells me that I have a bad address.

The problem I have is I never got a notification (non-delivery email) back.
Should I have gotten one? I do if I send an email not using Astaro.

Thanks,
Joe

    Hi, Joe.  Are you sure your Mail Manager is showing bounces with 553?  Where would the Astaro SMTP send the email with an incorrect address?  When you send an email not using Astaro, are you using the same client and email domain/service?

    Cheers - Bob

    Hi Bob,
    Yes. Same domain and client outlook 2k.

    Where would the Astaro SMTP send the email with an incorrect address?


    Good question!!! I would hope to the senders address (Me) in the form of a new email or forward.

    I cant believe that the Astaro would just discard it and say "oh well".

    Are you putting your sender's IP in 'Authenticated relay' or 'Host-based relay'?

    When I send to an unroutable address, I receive the following message which includes the sent mail from "Mail Delivery System [Mailer-Daemon@FQDN-of-my-Astaro]":
    following address(es) failed:

      test@kjhdsfiuhcnwncoifgnewp.com
        Unrouteable address

    ------ This is a copy of the message, including all the headers. ------
    {I cut the rest of my test message}
