Ahoy Guix,

As of Guix commit 54278e225e99707c3bd6f9eb37b8906851251b49 alpine crashes 
while trying to send mail through a Microsoft Office365 SMTP server. The 
crash happens right after I enter my SMTP password. I've attached the 
debug output that pine writes when it crashes. I've confirmed that pine 
before that commit does not crash with the Office356 SMTP server. It seems 
to be particular to that SMTP server though, because the new pine does not 
crash when sending to an Exim SMTP running on a Debian stretch host.

Best,
Jack
