Package: msmtp
Version: 1.8.3-1
msmtp is capable of reading SMTP passwords in a conf file, using an
external command, or reading it on the TTY. So it tests by opening /dev/tty:
https://git.marlam.de/gitweb/?p=msmtp.git;a=blob;f=src/password.c;h=aa3b1b530e6e17f3e6d45b395bf399ba99924ecc;hb=HEAD#l198
However, the AppArmor profile prevents this, so in the default
configuration, msmtp cannot read the tty:
msmtp: authentication method PLAIN needs a password
msmtp: could not send mail (account xxx from xxx/.msmtprc)
It would be enough to add
#include <abstractions/consoles>
in /etc/apparmor.d/usr.bin.msmtp though.
