Emacs - Wanderlust

Wanderlust is also a mail client within Emacs. This post aims to summarize the procedure of its installation and configurations.

Wanderlust can be directly installed via ELPA. APEL, SEMI and FLIM are also installed as dependency.

We postulate that all the mails are stored in ~/.Mail, in which there are a plurality of Maildir folders, e.g., draft, queue, sent, trash, boc, edas, home, office, linkedin, r1, r1nr, rp. Mails are periodically fetched by getmail or offlineimap, e.g.,

*/10 * * * * /usr/bin/getmail --new --getmaildir=/PATH/TO/GETMAILRC --rcfile=GETMAILRC

or

*/10 * * * * /usr/bin/offlineimap -c /PATH/TO/OFFLINEIMAPRC -a ACCOUNT

In this case, following configurations are needed for wanderlust.

• ~/.config/emacs/init.el
