Works fine now with your suggestion. But now I am confused as to how to
correctly set this up. Do I still need to to set (nntp-authinfo-file
"~/.authinfo.gpg") for each secondary select method call? And if so,
where doe the epa set up come in? If you could explain how it fits
together that would be great.

e.g I have now


(require 'auth-source)
(require 'epa-file)
(setq epa-file-cache-passphrase-for-symmetric-encryption t) ;;VERY Important
(if (file-exists-p "~/.authinfo.gpg")
    (setq auth-sources '((:source "~/.authinfo.gpg" :host t :protocol t)))
    (setq auth-sources '((:source "~/.authinfo" :host t :protocol t))))
(setq 
      mml2015-encrypt-to-self t
      mml2015-cache-passphrase t
      mml2015-passphrase-cache-expiry 60000
      mml2015-verbose t)

(add-to-list 'gnus-secondary-select-methods
              '(nntp "motzarella"
                       (nntp-address "news.eternal-september.org")
                       (nntp-authinfo-file "~/.authinfo.gpg")
                       (nntp-port-number 119)
                       )
              )

so I am wondering where the auth-sources fits in now?
