Wrong Email From address if Email From display name contains "<>" and forwarded by Plesk

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Version 18.0.60 Update #1
AlmaLinux release 9.3

PROBLEM DESCRIPTION

When From display name contains "<>" (e.g. From: "<helloworld>" <test@sender.com), and email messages forwarded from one mail account to another on the same Plesk server, the original From will disappear and another "From: SRS" header is inserted.

Very few senders will write their display name like this, but we cannot force such senders to change their setting.

Tried below command but not help

plesk bin mailserver --set-outgoing-messages-fix-sender true

STEPS TO REPRODUCE

1. In Plesk, setup an email forward from test@recipient.com to test2@recipient.com
2. In sender's Outlook/webmail, set display name to contain "<>", e.g. From: "<helloworld>" <test@sender.com>
3. Send an email to test@recipient.com

ACTUAL RESULT

The original From will disappear and another "From: SRS" header is inserted.

Return-Path: <SRS0=gSvn=MQ=sender=test@recipient.com>
X-Original-To: test2@recipient.com
Delivered-To: test2@recipient.com
Received: by server.plesktest.com (Postfix, from userid 30)
    id 523FD80AB2; Tue, 14 May 2024 03:09:20 +0800 (HKT)
From: SRS0=gSvn=MQ=sender=test@recipient.com

EXPECTED RESULT

The original From remain unchanged

I could not reproduce the issue using Outlook (Desktop app) or Thunderbird as the sending application, only when using Roundcube as the sending application.

Filed the issue for further analysis with ID PPS-16007.

This has been confirmed as a bug. When fixed it will be published with ID PPPM-14438 on the Plesk change log. A possible workaround is to run the follow the command:

plesk sbin mail_handlers_control --disable --name add-from --type global --queue before-sendmail

 

[Kaspar@Plesk]

This issue has been solved with the release of Plesk 18.0.62.

When the email sender's address contains the < and/or > symbols, it is once again displayed correctly in the “From” field of a forwarded email. (PPPM-14438)
