When using the SMTP service Gmail rewrites your From:
address back to your original Gmail address. However you can add another verified e-mail address to your account, then Gmail's SMTP server will forward any From:
address that match.
- Log in to your Gmail account.
- Click 'Settings' along the top of any page, and then select the 'Accounts' tab.
- Click 'Add another email address' in the 'Send mail as:' section.
- Enter your full name in the 'Name:' field, and the email address you'd like to send messages from in the 'Email address:' field.
- Click 'Next Step >>,' and then click 'Send Verification' to complete the process. Gmail will send a verification message to your other email address to confirm that you'd like to add it to your Gmail account.
- Now go to your e-mail client software to setup your e-mail account.
- Under e-mail address, use one of the verified e-mails you've added to your Gmail account.
- Under outgoing mail smtp server, use smtp.gmail.com. Since it requires SMTP authorization, use your Gmail account as username (e.g. firstname.lastname@example.org) and your Gmail password as password. You can turn TSL on or off.
Don't forget that Gmail's SMTP places a limit on the number of e-mails you can send within a certain time period.
