Hmm, this should probably be considered a syntax error and therefore a
protocol violation. I'm currently playing around with a patch that will
allow you to configure strict syntax checking of MAIL and RCPT commands,
the original reason being to forbid the use of space between : and <, but
adding a check for non-ascii characters would seem sensible too.
