msmtp (1.8.2-1) unstable; urgency=medium

    /usr/bin/msmtp ships with an Apparmor profile restricting what the binary
    can access.
    If you notice Apparmor denial logs in dmesg, please report them as bugs or
    if they are specific to your environment, please add local rules to
    /etc/apparmor.d/local/usr.bin.msmtp and reload the main profile with:

    # apparmor_parser -r -T -W /etc/apparmor.d/usr.bin.msmtp

    The usage of secret helpers for the --passwordeval option is limited to
    gpg, gpg2, secret-tool, pass, etc. To use a different helper, edit and
    reload the main profile (/etc/apparmor.d/usr.bin.msmtp). If you'd like
    to disable the Apparmor profile completely:

    # apparmor_parser -R /etc/apparmor.d/usr.bin.msmtp
    # ln -s /etc/apparmor.d/usr.bin.msmtp /etc/apparmor.d/disable/
