Resolved Mail problem return path

[hume1991]

Server operating system version

Ubuntu 20.04.6 LTS

Plesk version and microupdate number

Plesk Obsidian Version 18.0.58

Hello, we have Plesk Obsidian Version 18.0.58, we now receive emails with no subject and instead of content with a return path at the beginning and then just code,
plesk repair mail -y has already been used without errors, plesk repair all -n also shows no errors, does anyone know the problem?

Best regards

DMARC problem see outgoing with dmarc. - CLOSE -

 

[Peter Debik]

Probably internal ID PPS-15447, we're currently researching the issue that may be linked with the ARC header addition since Plesk 18.0.58.

Good afternoon,
For the past 2 or 3 days, the emails we receive or send from Outlook desktop arrive without a subject, without a sender, and yet in the content of the message the headers appear:

However, from Thunderbird, outlook android or outlook web everything is correct... They arrive with the content.
They can help us?

 

[Jose Isla]

Could you post the full headers from Thunderbird (More -> View Source)? Would be very interesting what's before the Return-Path: header.

Is there a blank line before Return-Path:?

 

[Jose Isla]

No, it's a simple BR that I inserted to separate the message from the headers.

 

[hume1991]

Update: Despite correct DNS entries, emails arrive without a subject and with code content.
Checked: MX Lookup Tool - Check your DNS MX Records online - MxToolbox DKIM. Unfortunately you have to deactivate: Use DKIM spam protection system to sign outgoing email messages.

Best regards

[Jose Isla]

Thank you! @hume1991 ...but we don't understand your answer:
Do you mean to disable DKIM from our domain?

Thanks once again!

 

[hume1991]

Hello @Jose Isla,

For each domain, do Website & Domains, Email, Email Settings, select domain, remove DKIM check. It's under DKIM: Use DKIM spam protection system to sign outgoing email messages -> Remove check.

Then the emails should be correct.

Best regards

[Jose Isla]

OK thanks @hume1991 . Works!

But disabling DKIM is not a very good idea, in terms of problems we may have regarding authentication. No?

I suppose this solution is provisional, while they fix the problem.

Thank you so much!

Sounds like https://support.plesk.com/hc/en-us/articles/20464670313879/

 

[hume1991]

@Jose Isla

Excellent. It should only be temporary until the problem is resolved. Then activate again!

@Peter Debik

Thank you.

[Jose Isla]

Thank you.

 

[hobala]

Any chance to (at least manually) repair the mails? I could not find anything that describes in details what was wrong. BTW: How to apply "Update 1"?
