SignatureProfiler is a plugin for Apple's Mail application that adds missing features from the way that signatures are handled and managed with your outgoing mail messages, especially if you have multiple mail accounts (and who doesn't these days). It was originally written to make up for the complete lack of signature management in versions 1.x of the program, but even 2.x is still missing some capabilities if you use several different accounts and what to share signatures between accounts.
Once you have installed SignatureProfiler, you will be able to use the same signature to generate both of these different signatures, as an example:
Basically what this plugin does for you is add the ability to have replaceable tags in your signatures that are context sensitive to the Mail account that you are sending from. In addition, you can have it autofill information from iTunes into a signature as well. Each account can also have an entire replaceable piece that is used for that account only if a certain tag is in the signature. That's how the "Professional Assasin" appears above. It is what is called the "Tail Signature" for the Phil Anthro account.
The SignatureProfiler plugin is now available only for Tiger and Leopard and is a Universal Binary. The installer make a small change to the Mail preferences, if necessary, that needs to happen for Mail to recognize the plugin. The latest version (1.4.4) has only been released for Tiger and Leopard.

If you want to use SignatureProfiler on Mac OS X 10.3, you may download version 1.4.1, which was the last to support that version of the OS. The actual version of the Panther plugin is 1.1, but it was included in the 1.4.1 installer.
I enjoyed writing the SignatureProfiler plugin and, of course, use it regularly. If you also find yourself using it and like it, please consider making a donation via Paypal.
