bug#16727: closed (Re: bug#16727: Question. How do you deal with... You must set `rmail-search-mime-header-function')

[Don Warner Saklad]

a) For neophyte users unfamiliar with upgrading and programming on a system 
with GNU Emacs 23.3.1 how can neophyte users deal with...
    You must set `rmail-search-mime-header-function'

when trying...
    Esc-x rmail-summary-by-regexp

and then, for example set
    Regexp to summarize by: GNU/Linux

and get...
    You must set `rmail-search-mime-header-function'

b) For neophyte users unfamiliar with upgrading and programming what 
alternatives are there to an upgrade or reprogramming?

        >     (re-search-forward regexp nil t)))
        >

              How do you do that?... information for neophyte users unfamiliar 
with upgrading and programming please! What's rmailsum.el ?...
