Postfix bounces emails when sending

    I stumbled into this problem when trying to solve why one of our webhosting users could not send emails with PHP mail() -function. I noticed that the domain had DNS service on with invalid settings (dns hosting is not ours). First I assumed that was the problem since MX-records pointed wrong. I removed DNS service from the domain and even removed nameservers from DNS settings tab but no luck.

    When user tries to send email via www by using contactform (just a plain php mail form) I get this in my "psa/var/log/maillog":

    For some reason the emails originally sent to user.email@domain.tld get redirected to _plesk_bounce_domain.tld -address. This goes for all email addresses for this domain.

    - there are no email accounts set up for this domain in the system
    - dns service is switched off
    - I've tried removing the domain totally from plesk and recreating it

    Hi Igor, thx for the reply but unfortunately it did not help. Mails for the domain are still sent to _plesk_bounce -address.

    I stumbled upon another web client with same problem. All mails sent from php form are bounced back from _plesk_bounce address with the same error message.

    The problem that Jouni reported still exists - when sending emails from PHP, they are bounced to _plesk_bounce_domain.tld@@localhost.localdomain.

    This goes for local and remote recipients - we are using the postfix MTA.

    Any ideas?

    I figured it out a while back and ofc I forgot to post it here. This issue can be fixed by changing the domains mail settings. Navigate to:
    Domain in question -> Mail accounts -> mail settings
    and there you have the "email to nonexistent user" -attribute

    The domains with this problem had selected "bounce with message: yadda yadda yadda". Change that to "reject" and save the change and emails get sent forward to the correct servers.

    Hope this will help. :)
