I have sometimes more than 100000 tries a day from one host because of
temp rejects for stray newlines.
I usually place those in my local RBL for a permanent reject.

This is a Microsoft confirmed problem and they have a bug description
and fix.

P.S. Just found another one ... had
       1592 rejects: unknown:202.106.185.36 stray newlines
     the last few hours.
     220-smtp01.sohu.com Microsoft SMTP MAIL Version: 5.5.1877.197.19

P.P.S. Not accepting stray newlines is IMHO good for SPAM protection *smile*
     Most of the servers that get rejected this way are relay open ;-)
     The above smtp01.sohu.com:202.106.185.36 is relay open, too.
     452 additional rejects within the last 20hs *smile*
