I've been trying to figure out if this is a new "feature" or if there is an issue with my configuration. I'm using Ubuntu 10.04 Desktop with Postfix as MTA. My smtp (as opposed to smtpd) configuration follows that outlined in Jeremy's excellent response here:
Configure Postfix to send/relay emails Gmail (smtp.gmail.com) via port 587
I am able to successfully relay mail through [smtp.gmail.com]:587; however, on the receiving end, the from: address shows: "[my_gmail_username]@gmail.com" instead of "[my_user]@[my_domain]".
Would greatly appreciate any hints or tips; in this instance, my Google skills have failed me!
