Re: Pipelining vs. multiple failure codes

Yeah, I never saw an version of Outlook version pipeline an SMTP session.

The only "batching" I am seeing is from bulk spammers which ignore the
PIPELINING extension regardless.  But most will just drop the connection if
a negative response is provided at HELO simply because they don't seem to
understand a multi-line 220 greeting at the connection.

(Outlook gets this grievously wrong and will uselessly report to users
"Valid RCPT command must precede DATA". Not advertising PIPELINING
help because it pipelines anyway.)

Actually, Outlook *never* pipelines - if this happens, it's just a plain
bug.  What version of Outlook does this happen in?  I suspect you won't
find it happening in Outlook 2003.
