Comment (by bpetty):

 It's a reported bug a in an external library which should be reported and
 fixed upstream, and in this case, it was already reported and dealt with
 upstream, who's fix is already making it downstream in #21074.

 However, for the fix to actually work, WordPress needs to either set
 $phpmailer->UseSendmailOptions = false in wp_mail() by default (it's on by
 default), or it needs to expose the setting in some other way (turn on/off
 depending on new wp-option). Keep in mind that if it's turned off by
 default, it's not be a big deal that "-oi" isn't used, but "-f" won't be
 used either, and I believe that could break mail on more hosts than this
 fixes by turning it off.

 So, it's not a duplicate, but it does depend on #21074.
