Spoofing a From Address in SMTP
Hi, I am currently using Mailx to send a mail message from my unix account via an SMTP relay. This is working ok.
However from the recipient end the FROM address they see on mails received is <unix account>@<domain> eg
prod@liveserver.com
Is there anyway I can spoof this FROM address from the mailx send such that from the recipient end they see a different address ? I would like them to see
automailer@investserver.com
