I successfully installed zimbra on my server at home. I am receiving emails sent to my email address @ my domain, however when I send out an email it shows as if it is coming from the account I used for SMTP. I have internet through AT&T/SBC Yahoo so I use gmails SMTP server using my gmail account for authentication. When I send an email from firstname.lastname@example.org, it shows up as email@example.com which is the account I use for SMTP.
Can anyone please be of any help?
