In Outlook, if you look at the properties of the mail account, on the
"Servers" tab, is the "Log on using Secure Password Authentication" box
checked?  If so, try with it unchecked.

I believe you can setup a self-signed certificate, and then have it always
accept the certificate.

As root, you could do something like

cd /etc/ssl
openssl genrsa 1024 > private/server.key
openssl req -new -key private/server.key -out server.csr
openssl x509 -req -days 1461 -in server.csr -signkey private/server.key -out certs/server.crt
echo "ssl_cert_file = /etc/ssl/certs/server.crt" >> /etc/dovecot/dovecot.conf
echo "ssl_key_file = /etc/ssl/private/server.key" >> /etc/dovecot/dovecot.conf
/etc/init.d/dovecot restart

See

for more details on openssl certificates.
