Although RFC-822 discourages multiple occurences of header fields that aren't explicitly allowed, in practice there should be little ambiguity in what to do. Whereas if there were multiple DATE: fields, you wouldn't know what to do with them, it's pretty obvious what to do with multiple TO: fields. If someone clarified things and specifically ruled out multiple TO:, CC:, etc, fields, I sure wouldn't get too lathered up trying to get everyone to be compliant. If Qualcomm's mailer behaves as you described when replying to some messages, I'd be more inclined to blame the Qualcomm software than whatever produced the original email with multiple TO: fields. -- bill@attmail.com LZ 1C-320 bill@att.com (Voice/Fax) +1.908.576.2932 AT&T Labs / AT&T WorldNet Service
