Looking at the code, the line with the error is

  (string-match "[^- !#-'*+/-9=?A-Z^-~]" fullname)

where fullname is let-bound to

  (or name
      (and (boundp 'user-full-name)
           user-full-name)
      (user-full-name))

`name' is not provided according to your backtrace.  So I guess you have
somewhere in your init file

  (setq user-full-name 'mail-user-name)

whereas you probably wanted to write

  (setq user-full-name mail-user-name)

That is, you accidentally set `user-full-name' to the symbol
mail-user-name instead to the value of that variable.
