How exactly are you submitting email? smtp, sendmail/smtp, or sendmail/pipe? If it's the last one, then that interface has reduced functionality and things like Envelope-From won't work (and you only need that in very unusual circumstances and this doesn't seem like one of them); you'll have to look at your exim docs. --Ken -- nmh-workers https://lists.nongnu.org/mailman/listinfo/nmh-workers
