 Reporter:  fdik                   |      Owner:  (none)
     Type:  defect                 |     Status:  new
 Priority:  Normal                 |  Milestone:
Component:  contrib                |    Version:  2.6.4
 Keywords:  msmtp tls certificate  |       Port:  msmtp
-----------------------------------+--------------------
 With update to macOS Big Sur msmtp broke when checking server
 certificates. Sample:

 {{{
 % msmtp --serverinfo --host=smtp.gmail.com --tls=on --tls-starttls=on
 --tls-certcheck=off --port 587
 msmtp: cannot get TLS certificate info: error getting SHA256 fingerprint
 }}}

 Expected is this (sample from Linux box, formerly the same on macOS with
 MacPorts):

 {{{
 $ msmtp --serverinfo --host=smtp.gmail.com --tls=on --tls-starttls=on
 --tls-certcheck=off --port 587
 SMTP server at smtp.gmail.com (wq-in-f109.1e100.net [74.125.140.109]),
