MTA/Perl script for relaying only to Exchange-users

[Glenn Steen]

... And if one don't like/can use the commercial license of milter-ahead,
there is smf-sav (another milter)which one can configure to only do
recipient verification. Have never seen a performance comparison between
them, but I imagine they are pretty similar... And smf-sav had a pure OSS
license, last I looked (admittedly a while back:-).

Cheers!
