Mail signature with fortunes

Question

hi, everyone!
i want to add a random signature everytime i compose a new mail. this signature should be generated with the stdout put from the good old comand line tool 'fortune'.
i've already written an applescript that will do that but i don't want to execute the script everytime i want to write a new mail instead this should be done automatically evertime i hit compose mail.
i didn't found a solution yet and when i search for 'random signature' they always come up with the functionality to choose a random signature of all available sigantures... a bad solution might be to create 1000 signatures
have anyone of you an idea to realize that - with or without applescript?!
thx

Answer 1

first, you don't need the extra action to add attachments. if you drop some items on the saved application they will be passed to the "new Mail message" action as input and will be added as attachments. also, in my testing it seems that the processes of attaching the attachments seem to bump against the process of adding the signature. it get the same result as you originally but if I add a delay to the run applescript action then it works as it should so try
1. new mail message.
2. run applescript
on run {input, parameters}
delay 1
tell application "Mail"
set the message signature of (item 1 of input) to signature "My Signature Name"
end tell
return input
end run
