So the pdf file for mercury mail says that if you use the run a program option for a filter..
"The Run Program rule action will start the specified program, passing a temporary copy of the message on the commandline"
Well it's not working! I thought i was imagining it so i used a small test program i have for displaying parameters that are passed via the command line... no parameters are passed to it from mercury mail.
It does indeed start the program but it does not pass any parameters containing the email.
I really need this as i need to run a second mail server on the same machine on a different port (it's custom for another website and sends email via http to a url). If mercury can call another program and pass the email then the second program can simply pass the email via tcp connection to my other mail server.
Without the email being passed though, i'm unable to get this working.
