dovecot - Sep 2010 - Upgraded dovecot - now it insists on imap TLS

This is definitely an operator error issue, but I'm under a bit of pressure.

I updated our 1.1.20 installation to 2.0.1 over the weekend and 
discovered this morning that it's insisting on TLS imap on port 143 as 
well as port 993

What am I missing?

Thanks in advance
Alan

dovecot -n output would help.

It would, but I found/fixed the problem already.

I had to set the following:

protocol imap {
disable_plaintext_auth=no
}

The default has changed from "no" to "yes" between 1.1.20
and 2.0.1, but
the conversion routine didn't pick it up (the wiki Documentation 
suggests the default is still "no". Perhaps this should be updated?)

This still requires TLS on port 993, so there's no additional hole opened.

Ironically, we published plans some time back to disable local-access 
plaintext imap logins in October and have been warning users to change 
their settings but 90% of them hadn't yet done so.
