TITLE

Weird / Wrong(?) behavior for Reply-To when "Fix incorrectly set sender for outgoing mail" is set

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE

Plesk Obsidian v18.0.29_build1800200807.15 os_Ubuntu 18.04

PROBLEM DESCRIPTION

When you've set "What to do with mail for non-existent users" and "Fix incorrectly set sender for outgoing mail", there should be a Reply-To set, otherwise users have no chance to reply to the original sender.

STEPS TO REPRODUCE

1. Set "Fix incorrectly set sender for outgoing mail" in Server-Wide Mail Settings to true
2. Create Email address (Without Mailbox): postmaster@example.tld
3. Set forwarding of the just created Email address to your Email address (you@plesk.com)
4. Go to the "Mail settings"-Tab of the domain and for "What to do with mail for non-existent users" select "Forward to address" and use the just created Email address postmaster@example.tld
5. Sent an Email from somemailbox@somedomain.com to test@example.tld

ACTUAL RESULT

somemailbox@somedomain.com sents to test@example.tld.
test@example.tld doesn't exist, so it gets forwarded postmaster@example.tld.
postmaster@example.tld has no mailbox and because of the enabled forwarding it gets forwarded to you@plesk.com.
you@plesk.com receives the message from postmaster@example.tld.
The Reply-To isn't set.

EXPECTED RESULT

somemailbox@somedomain.com sents to test@example.tld.
test@example.tld doesn't exist, so it gets forwarded postmaster@example.tld.
postmaster@example.tld has no mailbox and because of the enabled forwarding it gets forwarded to you@plesk.com.
you@plesk.com receives the message from postmaster@example.tld.
The Reply-To should be set to somemailbox@somedomain.com.

Fixed in Plesk 18.0.31:

Sending an email from a mailbox associated with domain A to a mailbox associated with domain B that is hosted in Plesk with “Fix incorrectly set sender for outgoing mail” enabled in “Tools & Settings” > “Mail Server Settings” and forwards mail to a mailbox associated with domain C no longer changes the “From” header as if the email originated from domain B and not domain A.
