I use multiple email addresses for various reasons, but have all the mail come into one account. Mail.app handles this fine, but there is no way to link the signatures to the accounts. I seem to recall that there was a plugin to handle this awhile ago, but with Tiger mail, it wasn’t needed. My switch to IMAP seems to have confused Mail and now I have to manually switch the signatures to match the account.
Not being one to do manual things over and over again, I hacked up a Mail.app plugin that sets the signature based on the from name (the signatures are named the same as the from addresses). It didn’t take long and I’m not sure what I should do with this besides use it myself. Who knows what will happen in Leopard as this plugin uses undocumented APIs.
Am I such the exception that I have many email addresses and want 1 signature per address? I don’t need multiple actual email accounts (Mail.app handles the signatures with those), just multiple addresses for my multiple personalities.
I’d love to take a look at your hacked up plugin! I’ve been trying for weeks to get this functionality – I have two email addresses for one IMAP account with different signatures. Mail.app by default links signatures to accounts, not the from name, so I can only use one signature. I’ve edited the plist so many times I’m dizzy …
Let me think about releasing the plugin; I need to see what happens in Leopard and if my plugin is still needed.
