Delete a mail alias

This program simply removes a single mail alias from a virtual server. It
takes only two parameters, C<--domain> to specify the server domain name, and
C<--from> to specify the part of the alias before the @. Be careful using it, as
it does not prompt for confirmation before deleting. To delete the catchall
alias for a domain, use the option C<--from "*">.

No program exists for updating existing aliases, but the same thing can be
achieved by using the C<delete-alias> and C<create-alias> commands to remove
and re-create an alias with new settings.
