Toanswer several questions in one message:
- I can talk nicely to the MS SQL server (2000), tested with several other perl scripts on this machine. The script really is just this:

#!/usr/bin/perl
use warnings;
use DBI;
use Email::Store ('dbi:mysql:server=127.0.0.1;database=test','test','t
+est');
undef $/;
$mail = <>;
$/ = "\n";
Email::Store::Mail->store ( $mail );

Side-notes - SQL Translator gave me some errors when doing Email::Store->setup: SQL 2000 wants "col_name int identity" not "col_name identity int(11)" also for some weird reason it insisted on converting text fields to varchar(65535) so I created the needed tables by hand.
