Comment (by DJPaul):

 Extensive testing and experiment with @shanebp has revealed a fun quirk
 with PHPMailer. My current thoughts is that our PHPMailer implementation
 needs to match WordPress', so if anyone has had to configure server
 configuration to get `wp_mail()` to work, BudyPress' should just work.

 The only significant difference is that we set the `Sender` property, and
 WordPress doesn't.

 This was somewhat of an oversight because WordPress sets an email's `From`
 and `FromName` properties directly, whereas BuddyPress uses a method...
 which, by default, also sets `Sender` to the `From` address.

 From the following WP trac tickets (just the cream of the crop), there are
 calls for all these settings to be set one way or another, and setting
 `Sender` was tried and reverted years ago because it broke more than it
 helped:
