Mail log confusing - looks like emails are being sent with 2 "To" headers
In 5.10.4, the mail log is confusing. It makes it look like the email has 2 "To" headers.
Here's a redacted example ...
MIME-Version: 1.0
Content-Type: multipart/alternative;
boundary="=_xxxxxxxxxxxxx"
From: Us us@example.com
To: Donor Name donor@example.com
Subject: Receipt - Donating via credit card
Content-Disposition: inline
Content-Transfer-Encoding: 8bit
Return-Path: us@example.com
Date: Wed, 27 Feb 2019 09:07:39 +1100
Message-ID: civicrm_xxxxx.xxxx@example.com
