One of our user send an email and got bounced abck with the following error.
We are using Exchange Server 2003 and Outlook 2000. The setting in Outlook
is to use Plain text to write up the email.

Remote host said: 550 Error: Your email program uses "=20" instead of
spaces. Please correct this (try setting your mail program to use plain text)
and resend your message.

Anything I can do here. It only affect one destination email address only at
the moment.

The message that the remote host saw was generated by Exchange, not Outlook,
so that's where you'll have to look to solve the problem. You might want to
look at the server logs of the attempt to send the message and see if
there's something obviously wrong with what Exchange was sending - I can't
imagine that it would use "=20" in any of the SMTP protocol elements, so my
guess is that the remote server does not fully support MIME (the standard
message format nowadays).
