Issue 554 5.7.1 <test@domain.tld>: Relay access denied;

[matbcvo]

Hello

I am having problem with mail server. When someone sends email to email address that contains IDN domain, then they will get delivery status notification with error: 554 5.7.1 <test@dömäin.tld>: Relay access denied
Without IDN domain emails are delivered successfully.
For example when client has two domains (one of them is alias domain) and I send email to:
a) test@domain.tld -> email is delivered successfully
b) test@dömäin.tld -> I'm getting delivery status notification with error: 554 5.7.1 <test@dömäin.tld>: Relay access denied

Looks like the bug. I'd suggest you report it here with all the necessary details.

Unfortunately I can't create new thread in Reports subforum, because I'm getting:

Oops! We ran into some problems.

You have to post 5 useful posts here. After that, you will be able to post reports.

Thanks, I'll submit report as soon as possible.
I'll include postfix configuration, maybe someone finds something wrong in that configuration.
/etc/postfix/main.cf

Sounds like your virtual domains file for postfix is not correct, have you tried 'plesk repair mail -v > logfile.txt'. That might reveal what is amiss.

It's actually Plesk bug, which will be fixed in next Plesk update, and here's fix: Forwarded to devs - 554 5.7.1 <test@dömäin.tld>: Relay access denied;
