Comment 4 for bug 1652183

This is getting pretty urgent. I spent the last few hours investigating. Here's something I saw.

In production, the latest update works fine for email that is generated from a web form. Meaning, in the browser, you go to a blog and make a post. It goes to osfkarl11 or 12, mailout runs, and it generates an outgoing mail with no problem.

But if you do email-in, it fails. Everything works on the Dec 4 update. But anything after that, fails. mailin picks up the incoming mail, generates an outgoing mail. That outgoing mail is rejected by postoffice with the above error.

I've narrowed it down to this. osfkarl11 (meaning web form) generates:

Reply-to: "A Time for Testing: Again"
 <email address hidden>
X-Actually-From: =?utf-8?q?karl=40osfkarl11=2Egocept=2Enet?=

...while osfkarl10 (meaning, mailin) generates:

Reply-to: "A Time for Testing: Again"
 <email address hidden>

I still can't find anything
