I found OpenSMTPd's implementation doesn't acknowledge "Resent-" headers.
Short description from Exim's man page: > If there are any Resent- header lines in the message, Exim extracts > recipients from all Resent-To:, Resent-Cc:, and Resent-Bcc: header lines > instead of from To:, Cc:, and Bcc:. This is for compatibility with > Sendmail and other MTAs. (Prior to release 4.20, Exim gave an error if > -t was used in conjunction with Resent- header lines.) Background: I'm a fan of Alpine's "Bounce" function as it enables me to share one or more mails in original form, in position in a thread. Alpine leaves the hard work to "sendmail -t". The effect of this is silently disruptive; in moving from Exim to OpenSMTPd I've been unwittingly re-sending messages to their original recipients. It seems there's at least some precedent for this (Exim man page mentions RFC2822) -- could this be added to OpenSMTPd? -- Mark
