Comment:
I see now that postfix is actually in the hostmakedepends for `check_mailq`. sqmail could be used for check_mailq but my build breaks if I try to use it instead of postfix (it first complains of missing useradd or groupadd, and after I add shadow to hostmakedepends for example chown and install gives Invalid argument), attaching log file for reference.

However, I don't think it's that important as `check_mailq` can also use postfix which the package currently does.
