fail to deliver a group mail --- "503 BAD SEQUENCE OF COMMANDS"
 

I created a contact folder "F" with 300 contact info, including myself and X.
I send the mail to myself , cc to X, and bcc to "F". It was sent out
succefully, however I received a system undeliverable message of "503 BAD
SEQUENCE OF COMMANDS" under each mail address of the recepient, including me
and X.

What is the problem?

Not possible. A folder cannot be an entry in a recipient field.

What version of Outlook? What type of account (SMTP, I'll assume from the
format of the error)? Do you have a mail scanner processing outgoing mail?
If so, disable it.
