Looking for fix to BSD mail problem with \".\"

[Chuck Collins]

Has anyone made the necessary fixes to 4.2 BSD mail that causes it to
interpret a "." in a reply address to be some sort of Berkeley-internal
network address? (Try replying to an address "name at any.x", it sends the mail
to some system named "onyx"!?) I just tried it on 4.3 and something different
occurs, which also looks wrong to me (cpc at any.x turns into any.cpc at x).

We thank you for your support
