Trying to setup the "e-mail-in node" to pick up e-mails only that are originated by one particular sender.
There is no such criteria in the menu, however there is an intriguing criteria
set from msg.criteria -
How do I set custom criteria using this menu item?
Hi - the underlying library is https://github.com/mscdex/node-imap - search that page for criteria should find you what you want.
(meanwhile I'l add a pointer to the info)
