if I try to fetch mails with pop3 without TLS (plain) then I will be always requested for the password and in the /var/log/maillog I see 

Feb 24 07:23:15 localhost dovecot: pop3-login: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=, lip=, session=<6+g/ldQPQwDVxlvV>

I checked the dovecot conf

disable_plaintext_auth = no
auth_mechanisms = plain login

this seems to be ok, but

ssl = required

I think this prevents the system from plain logins.
I changed to 

ssl = yes

And now I can login with PLAIN and with SSL/TLS.

@Michael: I think always SSL/TLS would be good but not every user is using it. So I think this should be yes and not required.
