good, and you are not running 3.35 (pfew!) but 4.20:

220 flizzle.net ESMTP Exim 4.20 (Debian package 4.20-0cmeerw) Mon, 07
Jul 2003 18:33:44 +0100

but:

...
rcpt to: <this was postmaster>@brandarisstation.net
421 Unexpected failure, please try later

of course the local part was postmaster... what did you do to the
poor configuration?
