Consider a pre-generated text file sample.eml like this one: From: Bob <[email protected]> To: [email protected] Subject: foobar
The message body goes here... Imagine further that Bob is logged in as user123 on host.example.net which runs Postfix, and Bob sends the message like so: $ /usr/sbin/sendmail -t < ~/sample.eml This would typically result in an envelope sender address like <[email protected]>, which may not be reachable from the outside. To force a different envelope sender address, Bob could use the following: $ /usr/sbin/sendmail -t -r [email protected] < ~/sample.eml This can of course be automated by extracting the "From:" header value from sample.eml, e.g. in a wrapper script which then calls sendmail with the appropriate "-r ..." parameter. I wonder however if this is something which sendmail can achieve out of the box, without the need for a wrapper script? The sendmail(1) man page doesn't seem to indicate that there are parameters for this use case, but I thought I'd ask here. By the way, I have considered sender_canonical_maps, but if each userNNN can use several different valid From: addresses (all valid), canonical address rewriting does not seem like the right tool? -Ralph _______________________________________________ Postfix-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
