Is this real or is just a changed banner?
It is real. Microsoft bought Frontbridge, which is now "Exchange
Hosted Services" or something like that. The MX hosts for Frontbridge
are Postfix servers. The MailStore for hosted customers is typically
Microsoft Exchange.
It is possible that in the future, just as with Hotmail, Frontbridge
will have to migrate to an all Microsoft stack. Hotmail originally ran
on FreeBSD IIRC. Most people probably never knew or no longer remember
that Hotmail was once not Microsoft.
The MTA at Frontbridge was a heavily customized Postfix 1.1 last time I
looked (long after it should properly have been 2.x, but I guess they
modified it too much to make the migration to 2.x worth their time).
Thanks so much Víctor.
