I'm not sure if this is in the right forum.
I have a Couier IMAP server
Its setup as Fetchmail > Postfix > IMAP > Squirrelmail
Fetchmail picksup my emails from a POP3 server and then I use squirrelmail or Outlook to read/write my mail.
My problem is when I send mail from squirrel or Outlook the received email comes from email@example.com
Home is my login.
What I want it to come from is my ISP email address ie firstname.lastname@example.org
I looked at postfix readme + google etc.
Is it MX records / alias and if so how exactly do you set it up.
Any help would be great
