I'm afraid it's a bit "some-assembly-required", but let me mention one possible solution. At least if you just want to have a regular expression match on the recipient, then the example configuration in message-templ [1] may be enough to get you started. You'd have to either call message-templ-config-exec in a hook, or bind it to a key and call it manually to set up the headers before sending. [1]: http://pivot.cs.unb.ca/git?p=message-templ.git;a=tree
