It shouldn't, since the "local part" of >the message-id (before the "@") is case-insensitive. Sigh... I must start getting 8 hours of sleep a night. The situation is actually more complicated. The rules (RFC1036 and 822) say that the domain part -- after the "@" -- is case-insensitive, but the local part -- before the "@" -- is case-sensitive except for some odd special cases. So one would think that case distinctions in the local part would be okay. Unfortunately, B2.11 considers *both* parts case-insensitive for some bizarre reason, and 2.11 is much too widely distributed to ignore. -- Mars can wait: we've barely | Henry Spencer at U of Toronto Zoology started exploring the Moon. | uunet!attcan!utzoo!henry henry@zoo.toronto.edu
