--- Comment #12 from D. Stussy <[email protected]> --- There is no conflict with the RFC. The "Sender:" header is clearly OPTIONAL (but discouraged) when there is a single mailbox identified in the "From:" header. It is clearly REQUIRED when there are multiple mailboxes in "From:". -- You are receiving this mail because: You are the assignee for the bug.
