I don't remember exactly if we encourated the problem with 1.17 (seams not
in my mind)
(but can be explained because we didn't had many traffic directed to hotmail
at 1.17 time)

Yes
The problem is EXACTLY 'XMAIL comes back to the A record for obscur reasons
(internal or due to bad dns responses ?) even if MX records exists for the
target domains'.

In my current configuration, xmail 1.21 forwarding ALL traffic to a Symantec
SMTP AV Gateway USING the SAME Microsoft DNS SERVERS, then ALL TRAFFIC IS OK
(except usual errors, timeouts, ...)
In another 'old' configuration, we used a Microsoft (yes!) Iis SMTP server
using the same dns sservers and all was ok too !!
