The RFC5322.From header may contain multiple addresses. If the From: field contains more than one address, the Sender: field *must* be present. So, I believe, you should check From: *and* Sender: Best regards from Dresden/Germany Viele Grüße aus Dresden Heiko Schlittermann -- SCHLITTERMANN.de ---------------------------- internet & unix support - Heiko Schlittermann, Dipl.-Ing.
