+   This snippet filters stale addresses from address completion; I
+   found this method [[https://emacs.stackexchange.com/questions/47789/how-to-remove-email-address-from-local-database-in-mu4e][here]].  The code loads the definition of
+ ~filter-addresses~ from an external file and checks if ~addr~ is
+   one of the addresses in the list.
+
+   #+begin_src emacs-lisp
+     (load-file "filtered-emails.el")
+
+     (defun my-mu4e-contact-filter-function (addr)
+       (let ((ignore nil))
+         (if  (dolist (address filter-addresses ignore)
+                (setq ignore (or ignore (string-equal addr address))))
+              nil addr)))
+
+     (setq mu4e-contact-process-function 'my-mu4e-contact-filter-function)
