No, it doesn't.

It's more than that.  The "550" error is coming from a RCPT TO: command,
not from a VRFY.  No, your ISP simply does not have a "postmaster", at
least for that domain.  That violates RFC822.

I was not able to send mail to "postmaster at newcenturycomputers.net".  It
failed with a 550 user unknown.
