Your favorite Emacs mail program is not supported? Shame on me. But it is really easy to integrate other mail programs into mairix.el. Just do the following:
Write a function that displays the mairix search results. This function
will be called from mairix.el with the mail file/folder as the
single argument. For example, the function mairix-rmail-display
is currently used for RMail and mairix-gnus-ephemeral-nndoc is
used for Gnus.
Write a function that retrieves a header from the currently active mail.
The single argument for this function is a string with the header name.
For examples, see mairix-rmail-fetch-field and
mairix-gnus-fetch-field for RMail and Gnus, respectively.
Add your mail program to the defcustom of mairix-mail-program.
Then add the functions to mairix-display-functions and
mairix-get-mail-header-functions.
...so that I can eventually integrate it into future versions of mairix.el.
And that’s it!
