metamail.aarch64: W: call-to-mktemp /usr/bin/metamail
This executable calls mktemp. As advised by the manpage (mktemp(3)), this
function should be avoided. Some implementations are deeply insecure, and
there is a race condition between the time of check and time of use (TOCTOU).
See http://capec.mitre.org/data/definitions/29.html for details, and contact
upstream to have this issue fixed.

metamail.aarch64: E: spurious-executable-perm (Badness: 50) /usr/share/man/man1/mgrep.1.gz
The file is installed with executable permissions, but was identified as one
that probably should not be executable.  Verify if the executable bits are
desired, and remove if not. NOTE: example scripts should be packaged under
%docdir/examples, which will avoid this warning.
