If i send 100 mails , approximately 40 - 60 mails are delivered, remaining are soft bounce with any the following errors

550 5.7.0 (BAY0-MC1-Fxx) Message could not be delivered. Please ensure the message is RFC 5322 compliant.,mx4.hotmail.com

We just started seeing them as well and have not figured out what they mean yet.

550 5.7.0 (COL0-MC2-F34) Message could not be delivered. Please ensure the message is RFC 5322 compliant.

Did you check if your email is RFC 5322 compliant?
http://tools.ietf.org/html/rfc5322

I did ran a Google Search and found this for example:

Quote
Reply-To: header. My software was using:
Reply-To: (Firstname Lastname) username@my.domain

Changing this to the following appears to have solved my problem:
Reply-To: Firstname Lastname "angle"username@my.domain"angle"
