I want to allow senders to unsubscribe to mail lists. I want them to be
able to send in the format
unsubscribe listname
:0i
* ^^Subject:.*unsubscribe \/[^^ ]+
I wanted to know if it was possible to validate the name of the
list($MATCH) with an entry in a text file located in the file system? This
text file would contain valid list names. If the list name was in the text
file then it would do something, if it wasn't in it would do something
else.
How would I do this using Procmail?
Thanks
