I too would greatly benefit from the idea here, and was going to post similar, but used the forum search instead.
To be able to use POP3 or IMAP, download email/attachments/inlines and save them off to files, or parse the contents, would be extremely nice.
With the option to to base processing criteria based on from/to address, subject, or all, and the option to delete the original messages after processes.
This could actually cut out a number for processes we currently have a programmer maintaining.
Thanks!
