Fixed 5.7.1 Recipient not found processed as Soft Bounce

[Alpha1]

Affected version

2.3.7

This clearly should be a hard bounce:

Action: failed
Final-Recipient: rfc822; xxx@tutanota.com
Diagnostic-Code: smtp; 550 5.7.1 <xxx@tutanota.com>: Recipient address rejected: Recipient not found
Status: 5.7.1

 

[Alpha1]

To elaborate:
The text Recipient not found does not match any of the entries in \XF\EmailBounce\Parser::$invalidMailboxStrings.

Thank you for reporting this issue, it has now been resolved. We are aiming to include any changes that have been made in a future XF release (2.3.10).

Change log:

Ensure "Recipient not found" bounce responses are classified as hard bounces

There may be a delay before changes are rolled out to the XenForo Community.
