RFC 822 Standard for the Format of ARPA Internet Text Messages 3.4.7. Case Independence (lists what is excluded from the standard case insensitive rules. One of the items listed is "local part" which is the portion before the @ sign in an email address. Also specifies that "postmaster" is the exception to the local part rule, and must be case insensitive.) So it looks like Bill is in fact correct. The username portion of an address can be case sensitive if the mail server admin so chooses to do so. I think in standard practice, you won't find many "public" servers set that way (by public, I mean something a regular internet surfer could send email to)... simply because I think most admins try to assume standard users are idiots, and requiring certain case to be used will just cause problems. But, none the less, an admin can choose to make mail boxes case sensitive if they wish. -chris <http://www.mythtech.net> ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
