[Dovecot] Fedora 16 configuration

[Cliff Hayes]

Hello,

I am trying to get dovecot to work on a fedora 16 install with sendmail.
I have been able to get it to work in the past with dovecot.conf but not
with the new conf.d directory and associated config files.
I keep seeing this in maillog:

Feb  7 14:28:59 sendmail dovecot: pop3-login: Aborted login (no auth
attempts): rip=x.x.x.x, lip=x.x.x.x

And the mail client comes back with username or password invalid.
Is there instructions somewhere regarding fedora 16 installs?
I found this one and tried it to no avail:

Thanks in advance,

Cliff
