Hi Chris,
I am using version 2.3. I want to have multiple signatures for a couple of business accounts. I created one signature and saved it in a do not. I want to create another signature for another account. Is there a way to link up that one signature for one account and the other signature for another account? I am assuming that I have to create two different todo note files for this purpose. Thanks.

There is no automatic switch for Email account signatures depending on the account used.

The easiest method is to use the Drafts/Templates feature. On the right side of the Email Message window is a hidden panel that can be exposed using the icon.

You can also manage and edit the draft templates using the Messages folder/navigator tree.

Just compose a new message template for each account then insert which template you want to use when make replies.

To save the template, just use the "Save To Drafts/Templates" command in the edit window.
