Multiple identities per e-mail account

You can tell Thunderbird to use more than one identity per mail account. This would be the case where you have a catch-all account for a domain or forward messages from another e-mail address. The instructions below assume that you have Thunderbird 0.7 or higher.

1. Go to Tools -> Account Settings.
2. Choose the account that you wish to add additional identities to .
3. Click Manage Identities (the button is on lower right).
4. Add the additional identity that you want.
5. Repeat as necessary for additional identities.

Now, you can select any of the identities when replying to mail or composing a new message.
