No, you would need to leave it running so we can figure out what's causing it and then fix it.

@Chris D I've attached a SQL file for inserting the broken entry into the bounce log. I don't think there's any PII / non-ephemeral keys in the message, and the email appears to be attached to a spam bot so I don't think I'm leaking anyone's valid emails. If I'm wrong, feel free to edit the message after you have the info you need :)

Actually, it may not be Spamassassin but it looks to be caused by whatever you have which adds the "X-Ham-Report" header.

@DragonByte Tech and @Tom are you both running "Spam Assassin" on your server/mail server?
I believe so. It's a WHM / cPanel server, using these settings:



Global settings:



I will try disabling SA for that particular account, as the domain we use for bounce handling is not used for anything other than that.

If so, can you provide details on which version etc. if available?
I've no idea how to find the version in WHM 🤔

We're running the latest WHM (v74.0.5 on CentOS 7.5).

---
I'll try registering with a fake email and see whether it processes this bounce successfully.

Confirmed that SpamAssassin is a potential culprit for this:



It should still be fixed just for maximum compatibilityness sake, but at least I can bin my custom code now 😄

Well, strictly speaking, Spamassassin isn't actually doing anything wrong. It mostly seems to be an issue with Zend Mail and their over-zealousness when parsing the mail headers.

It's quite possibly a major PITA to fix.
 

Chris D

XenForo developer
Staff member
Well, it became less of a PITA because we've forked Zend Mail and we're now using that in XF 2.0. We've also submitted an issue for consideration for future versions of Zend Mail which we should be able to use in XF 2.1.

Either way, we'll call this fixed for the next release.

I'm having a similar issue as well, and we are also running SA on our server.
