When called over systemd, pass will not display a pin-entry field to
decrypt the necessary passwords for email synching.

-- According to the IMAP specification, when trying to write a message
-- to a non-existent mailbox, the server must send a hint to the client,
-- whether it should create the mailbox and try again or not. However
-- some IMAP servers don't follow the specification and don't send the
-- correct response code to the client. By enabling this option the
-- client tries to create the mailbox, despite of the server's response.
-- This variable takes a boolean as a value. Default is “false”.
