Citar:I'm a Gmail or Google Apps user sending from an external address.

1. Click the gear icon in the upper right, then select Settings.
2. Select the Accounts and Import tab (or Accounts tab, if you're using Google Apps).
3. Under Send mail as, click Add another email address.
4. In the 'Email address' field, enter your name and alternate email address.
5. Choose one of two options:
-Use Gmail's servers to send your mail (this is easier to set up)
-Use your other email provider's SMTP servers (we recommend this option for professional mail accounts or domains). Note for Google Apps users: Depending on your domain type, this feature may be disabled by default. Talk to your administrator if you have any questions.

If you choose to use Gmail's servers:

6. Click Next Step >> and then click Send Verification. Gmail will send a verification message to your other email address to confirm that you own it.
7. Open your other account and either click the link in the message Gmail sent or enter the confirmation code in the Accounts section of your Gmail settings.
If Gmail sends a verification email and you didn't receive the it, the message was probably caught by a spam or bulk mail filter in your recovery email system. Try checking your Spam or Bulk Mail folders for a message from account-verification-noreply@google.com to see if the email ended up in there.

Your Gmail address will still be included in your email header's sender field, to help prevent your mail from being marked as spam. Most email clients don't display the sender field, though some versions of Microsoft Outlook may display "From yourusername@gmail.com on behalf of customaddress@mydomain.com." For this reason, if you don't want 'on behalf of' to appear in any of your messages, we recommend using the SMTP servers of your other email provider.

If you choose to send mail through another domain's SMTP servers:
6. Enter the SMTP server (e.g. smtp.domain.com), your username on that domain, and your password for that account. You may also need to adjust your port setting or SSL setting (talk to your other ISP if you need this information).
7. Click Add account >>
8. Open your other account and either click the link in the message Gmail sent or enter the confirmation code in the Accounts section of your Gmail settings.
Your other email provider has to provide authenticated SMTP support for you to use this option. We'll use TLS by default, or SSL if you enable it. Many email services that provide POP6 or IMAP7 support also offer authenticated SMTP support, and you can likely find your SMTP server configuration instructions alongside information about POP or IMAP. Also, this new version of custom 'From:' doesn't work with Yahoo! Mail Plus accounts just yet, but we've reached out to Yahoo! to try to get it working.
