How to send from different addresses in Mozilla Thunderbird?

Posted on 2007-11-14

Hi, I have like 27 million different email addresses. And I want to be able to select which email address the recipient sees _each time I send an email_.   For example, when I send to my boss, I want it to be my work address, and when I send to my friends, I want it to be my personal address.  

I have all my incoming mail from all these addresses forwarded to one imap server.

In the past, I've used Pine to do this perfectly. Pine supports "roles" which allow you to select which address you are sending from. Plus, pine is very smart to automatically select the best role based on a variety of info in the headers.  

But I need to switch to Thunderbird. Is there a way to do this in T-bird?

Hello highqllc,

You need to set up account for each address. The in Reply box, change From address to the address you want.

Hope this helps!

Hi war1,

When I try to add a new account, I get the following error: "A mail or newsgroup account with the same user name and server name already exist. Click Back and enter a different server name, or click Cancel"

Let me give you an explicit example.  

A1)   fwd->
A2)   fwd->

So, I use the server as my incoming server. And my username there is 'blah'.  So, when I try to set up two accounts, one for A1 and one for A2, T-bird gives me that error.

If an email was sent from UCSB account, forwarded to an IMAP server.  In TBird, set up an UCSB account. It should be different than other accounts. Set same for work and other addresses. Then you can select which account to send from when you reply.

Sorry, I'm not quite on board with you.   I cannot set up a UCSB account because T-Bird asks for the incoming/outgoing servers for that account.  However, I neither send  nor receive email at UCSB.  What I mean is that although I have an address,, all email sent there is immediately fwd to  So, I only check email at and I only send email from

Are you suggesting that I just put in dummy values for the incoming/outgoing UCSB server information?

Hi there,

What I think you need is a Thunderbird extension (add-on) called "Virtual Identity"

You may also want to check out the extension called "Correct Identity" which is a useful addition to the above:
