According to RFC 5322: from = "From:" mailbox-list CRLF mailbox-list = (mailbox *("," mailbox)) / obs-mbox-list Thus, one From: header may contain multiple addresses. Wietse

Right, but I think OP was asking if one set of mail headers could contain multiple From: headers. -- 'You don't think you've had enough, do you?' he said. I KNOW WHEN I'VE HAD ENOUGH.

Well, another possible trouble I was about to ask later, but still, can there be multiple From:? And in what cases can there be multiple addresses in From: field? Its strange. If anyone knows...

Its strange. > If anyone knows... RFC 5322 speaks of the From: field in singluar only, thus only one is allowed: The originator fields of a message consist of the from field, the sender field (when applicable), and optionally the reply-to field. The from field consists of the field name "From" and a comma- separated list of one or more mailbox specifications. -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt(a)charite.de | http://www.charite.de |
