Oh yes, it is. We have MS Outlook Express and Outlook clients and they
connect without problems. Do two things:

1: telnet mail.barlaeus.nl 25
    ehlo mydomain.net

    See what it says.

2: openssl s_client -starttls smtp -connect mail.barlaeus.nl:25

    See what it says.

You need the "AUTH=LOGIN" for the MS client to recognize it. You
therefore need broken_sasl_auth_clients = yes in main.cf.

What the bleeding heck does that have to do with the price of fish?
