* Modifications to protect the privacy of users:
+ Alpine does not generate Sender or X-X-Sender by default
by making [X] Do Not Generate Sender Header the default.
+ Alpine does not disclose User Agent by default by making
[X] Suppress User Agent When Sending the default.
+ Alpine uses the domain in the From: header of a message
to generate a message-id and suppresses all information
about Alpine, version, revision, and time of generation
of the message-id from this header. This information is
replaced by a random string.
