Comment 3 for bug 141641

This was discussed several times already (also see upstream bug). One workaround is to only depend on a particular lsb submodule.

However, the entire idea of requiring an MTA is pretty impractical. A cripped MTA like nullmailer would basically just send mails to /dev/null, and a real MTA like postfix is a potential security hole.

The actual flaw here is that it encourages applications to rely on being able to send local mail, forget about it, and assume that the user actually read it.
