I tried fiddling with PAM by adding an /etc/pam.d/apop file with these contents :
It's impossible to support anything but plaintext authentication with PAM. See http://wiki.dovecot.org/Authentication/Mechanisms and http://wiki.dovecot.org/Authentication/PasswordSchemes
I'm not overly worried about PAM; I just want to get APOP working. But the wiki doesn't give me even the faintest idea, keeping in mind that I am relatively new to linux. The same applies to all the other authentication schemes. It only tells me how to change the conf file, which doesn't appear to be enough.
Obviously I am missing something here. But I don't know what.
You still haven't provided concrete details of your system (dovecot version, and/or dovecot -n output)...
Read this page, and search on 'apop' - maybe it helps...
