Why should an MUA care about some local interface at all ?
It doesnt say anything whether the server can be reached, it's
nothing more than guessing, that *might* be fine for trivial
setups but can cause big headache in more complex ones.

For example:

* LAN is up, but remote server is or LAN's uplink down,
  MUA wont learn about it this way
* local mailserver is falsely considered unreachable just
  because the LAN interface went down

There's no way around it: the MUA (or a local proxy) must
always check on itself whether a _particular_ remote server
is reachable and properly handling that.


And *IF* some application is interested in the such information,
why not just using the filesystem ?
