    Falko HELP!!! LOL

    Alright so i just made the changes in the /etc/postfix/ what i did is as follows:

    changed myhostname = server1.$mydomain
    myhostname =

    also changed mydomain =
    mydomain =

    (I used "mail." in stead of "server1." because server1 still did not allow messages to aol but using "mail." aol accepted my mail messages so that worked GREAT!

    BUT i had to change it all back to because my server became as slow as my OLD commodore64 was working non stop and in my own personal mail box on the domain i kept getting the following message sent over and over about 300 per hour:

    ----[mail message being]----------
    This is the Postfix program at host

    I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.

    For further assistance, please send mail to <postmaster>

    If you do so, please include this problem report. You can delete your own text from the attached returned message.

    The Postfix program

    <[email protected]> (expanded from
    <[email protected]>): mail for loops back to
    ---[mail message end]--------

    I'm getting these in my mail box (never got them before) about every 25seconds PLEASE HELP its slow and a ton of these same message filling up my mail.

    How do i get that undeliverable message to stop happening? and my server still now runs REALLY REALLY slow unless i stop the postfix in the command prompt.

    Please help! thanks!

    Just append to the mydestination line in /etc/postfix/ and restart Postfix.

    just tried that my MYSEDTINATION is as follows:

    mydestination - /etc/postfix/local-host-names

    and i restarted the postfix but still getting message of undeliverable and other people on differant domains than "" are now calling saying they have 400+ of these messages in their inboxes too..

    What next? thanks for the help!

    This setting of mydestination wont work. If mydeatination is a path like: /etc/postfix/local-host-names, must open the file /etc/postfix/local-host-names and add the line:

    at the end of the file instead of appending it to mydestination in your file.

    Does the mydestination line looks like this:

    mydestination = /etc/postfix/local-host-names

    and not with a "-" inside like you posted it in the forum?

    mydestionation = /etc/postfix/local-host-names

    What's in /etc/postfix/local-host-names?

    (it also included but took it out as that really slowed the system down and produced even more undeliverable messages)

    # ISPConfig local-host-names Configuration File
    # Version 1.0

    Im at wits end...i stop the postfix server then run the postsuper -r ALL and it nukes hundreds of messages. then restart the postfix for less than 1 minute stop it and the postsuper will still remove about 190+ messages.

    WHat is creating this message replication of undeliverable for all users on all domains? it is killing us.

    Can you post a more detailed excerpt of the mail log?

    Falko & Till, Thanks for all your help and quick responce. I had to give up and build out a new server cloaning this one.

    This thread started out because any domain on my server could not get emails through AOL or Timewarner that were sent from a PHP program. Well on the new server i rebuilt i installed it correctly in the fact that i named the server build "" versus the original machine that was "".

    so now AOL, timewarner no longer block emails from my new machine...48hours of stress and pain but a heck of a learning experience! LOL

    thanks again you two for all the help! till next time....
