+Email Setup
+-----------
+
+WuttaFarm can send emails of various kinds; of note are:
+
+* when user submits Feedback via button in top right of screen
+* importer diff warning for farmOS → WuttaFarm
+
+That last one is optional, triggered via the ``-W`` flag in the
+importer command line.
+
+Anyway the app basically assumes there is a Postfix or similar mail
+server running on "localhost" which it can use as the SMTP server, and
+which is in turn responsible for "really" sending the email out via
+some configured relay.  This has always worked very well for me since
+I tend to want to have email working for other reasons on each Linux
+server I maintain.  (And since I have not traditionally used Docker
+and/or containers.)
+
+So if you need something else, touch base and we'll figure something
+out.  But assuming localhost is okay to use:
+
+In the web app menu, see Admin -> App Info and then click Configure.
+Check the box to enable email and plug in the default sender and
+recipient (which should be the admin responsible for the app).  I
+often create an alias so I can use e.g. wuttafarm@edbob.org as
+sender - aliased back to myself in case it generates bounces so I can
+see them.
+
+From there you can also see Admin -> Email Settings in the menu; this
+lets you control and preview each type of email separately.
