gnus: Connecting to an IMAP Server
6.3.1 Connecting to an IMAP Server
----------------------------------
Connecting to an IMAP can be very easy. Type ‘B’ in the group buffer,
or (if your primary interest is reading email), say something like:
(setq gnus-select-method
'(nnimap "imap.gmail.com"))
You’ll be prompted for a user name and password. If you grow tired
of that, then add the following to your ‘~/.authinfo’ file:
machine imap.gmail.com login <username> password <password> port imap
That should basically be it for most users.
