Outlook Express and AUTH

[Ilya]

Hey. I just tried to use "Logon using secure password authentication" option
in OE and got a syntax error from server. Afteri logged what OE was actually
sending i found out that it sends "AUTH " no quotes, but an EXTRA space in
the end. This space screws the whole thing.
So my question is : is this space allowable by RFC or is it M$ wiked game
again?
anyone knows of the way around it?

thx
