Subject: guix: add local dovecot mail server to chaman
X-Git-Url: https://git.shemshak.org/~bandali/configs/commitdiff_plain/a225edd9cbe2a14e8461bc64bb78ab3bf8fbefb1?hp=0b6b7db2bcad323ddfc5132b45ba771f65279948

guix: add local dovecot mail server to chaman

note: the dovecot/auth process runs as a non-root `dovecot' user,
which needs to be able to read the passwd file.  therefore, the file
itself needs to have the read bit set accordingly, and its parent
directories need the executable bit.
