 I don't think it's certain that the double `-f` problem is the only issue
 here.  [https://core.trac.wordpress.org/ticket/64368#comment:7 This
 report] sounds like it is the double `-f` problem, but
 [https://core.trac.wordpress.org/ticket/64368#comment:5 this report]
 sounds like it's a deliverability problem instead.
 [https://core.trac.wordpress.org/ticket/64367 This report] might be either
 one - it's hard to tell.
