"Error: Could not get login password entry response" I am having the same exact problem, my courier is IPV6 enabled. I started by disabling IPV6 in Postfix, but now I can't figure nor find how to disable the IPV6 support in Courier. (Only thing I found is how not to enable it during configure) Any pointers would be appreciated. By the way, I am using Debian Etch. Thanks - Qwertz
I also had this Error: Could not get login password entry response Solved by going to Management -> server -> settings -> email and set Maildir = on then login with username (not email) an password.
