New version out. I'll look to see if just renaming the ebuild works, or if there's more to it.
Created attachment 573502 [details] courier-imap-5.0.7.ebuild Here's an ebuild for courier-imap-5.0.7 that I am using successfully. It works with courier-authlib-0.69.0-r1 and courier-unicode-2.1
Done. Thanks
