Looks as though you may have made it onto a blacklist - the last part in the transcript is a clue :

:Client host 195.92.193.207 blocked using Wed 2010-09-15 11:44:11: <-- 550-88.blocklist.zap; Mail from IP banned

There is an email address to request removal :

 To request removal from this list Wed 2010-09-15 11:44:11: <-- 550 please forward this message to delist.forefront@messaging.microsoft.com "

The server you are sending out from "smtp.dslgb.com" is blacklisted with some spam listing service. I presume this is your ISP's outgoing mail server so I would contact them with this transcript so they can get their IP removed from the blacklist.
