Transaction failed: Duplicate header 'Auto-Submitted'

[bengineer]

Affected version

2.2.15

I upgraded our forum 2 days ago to 2.2.15. Since then I have thousands of these errors:

Swift_TransportException: Email to xxx@aol.com from info@xxx.net failed: Expected response code 250 but got code "554", with message "554 Transaction failed: Duplicate header 'Auto-Submitted'. "

This has created a 46Gb mail queue, and has filled my unix disk, making the site unusable. I've had to disable mail in the meantime.

Help!

I also uninstalled
#7 src/addons/Andy/EmailLog/XF/Mail/Mailer.php(10): XF\Mail\Mailer-&gt;send(Object(Swift_Message))<br>

But still have this issue.

We use Amazon SES for our mail relaying, and they are quite fussy about headers being correct.

I've commented out this line in src/XF/Mail/Mail.php (526) until a fix is provided:

# $message->getHeaders()->addTextHeader('Auto-Submitted', $this->autoSubmitted);

I also use Amazon SES and have the same errors. Currently 20 odd pages, but if I clear, they pop up very quick and consistently.

I am getting the same thing since I upgraded.

In my case, it appears to be triggered by the Register Email XF2-Addon. I'll contact Andy with details to investigate.

Note that once the bad email ends up in the queue, there's no way to flush it without applying the fix in post #2 above (https://xenforo.com/community/threa...ate-header-auto-submitted.219501/post-1668415)

 

[btmgreg]

Is this like an undocumented change or something that addon devs need to fix? I honestly don't understand which side of the wall needs fixing. Hopefully we can get some insight?

 

[bengineer]

I'll report back. I guess the core software shouldn't introduce breaking changes to existing Add-ons. However, practically speaking, there's no way the XenForo team could validate all Add-ons against such changes. I'll report back on if my assumptions are correct or not.

@AndyB thinks it’s an issue with the patch. XenForo think it’s an issue with the addon.
