So what is the best way to work around this if there are many (long time) users using different email clients with different setups to connect to the servers.
If CRAM-MD5 is depreciated what about the others in the auth_mechanisms line below?
Has anyone added the below to dovecot.conf on DA yet and if so what is needed to make the non-depreciated ones work?
auth_mechanisms = plain login digest-md5 cram-md5 apop
or only is the correct way to go only auth_mechanisms = plain login over SSL/TLS?
