Looks like imaps and pop3s are listening only on all the ipv6 addresses configured.

localhost = usually synonym for ipv4 address 127.0.0.1

try connecting to:

::1

This should work, however you need to configure courier to not only listen to ipv6 addresses but also ipv4 ones.

Please start pop3 and imap. Currently, only pop3s and imaps are running.
