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

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Plesk Obsidian v18.0.34_build1800210305.11 os_CentOS 7
CentOS Linux 7.9.2009 (Core)

PROBLEM DESCRIPTION

Some of our customers have IDN domains (for example dömäin.tld). All emails that are sent to email addresses that contains IDN domain are getting rejected. Only emails that are sent to email addresses that does not contain IDN domain are delivered successfully.

One of our customer have 2 domains: domain.tld (alias domain) and dömäin.tld (main).
When I send email to:
a) domain.tld (not IDN domain) - email is delivered successfully
b) dömäin.tld (is IDN domain) - email is not delivered, I'm getting delivery status notification with error: 554 5.7.1 <test@dömäin.tld>: Relay access denied;

However it's possible to send emails FROM email address that contains IDN domain, but can't receive any emails.

STEPS TO REPRODUCE

Add IDN domain
Create email address that contains IDN domain
Send email to that email address

ACTUAL RESULT

Getting delivery status notification with error 554 5.7.1 <test@dömäin.tld>: Relay access denied

EXPECTED RESULT

Email should be delivered to that email address that contains IDN domain

Help with sorting out

 

[IgorG]

Thank you, Bug confirmed PPPM-12866

 

[matbcvo]

I would like to fix that asap as our customers need working email address for their business. Is it possible to apply temporary bugfix until Plesk releases official update that fixes this bug?

 

[IgorG]

You can try to use:

postconf "smtputf8_enable = no"

I hope it will help.

 

[matbcvo]

Thanks very much, this fix helped, now they receive emails.

 

[ufo56]

You can try to use:

postconf "smtputf8_enable = no"

I hope it will help.

Same error here.
This fix worked but is this fix permanent or will be reverted with next plesk update ?

A fix for this bug is planned for the next Plesk update.

 

[Figrol]

Hello, this fix didn't resolve the issue for my domains. Is there another fix or any extra steps other than the postconf command?

When is the next plesk update? This is now affecting a large amount of users for us.

Thanks

Hi

See if your postfix/main.cf last line contains smtputf8_enable = no and restart postfix.

 

[Bitpalast]

@Figrol
# postconf smtputf8_enable=no
# postfix reload

To check whether the configuration line is in main.cf:
# grep smtputf8_enable /etc/postfix/main.cf

Fixed in Plesk 18.0.35:

Mail delivery to IDN emails no longer fails. (PPPM-12866)
