I set up dovecot and all is well, but before I decide that maybe I will set something up outside of my network, are all passwords secure? should I only use new created users with no special permissions? I set up dovecot.conf with auth = default and in default { } the default value is md5-digest but when I try to select that option with evolution I get this: "unable to connect to POP server $Server_Name: no support for requested authentication mechanism" and it will only work on evolution if I pick "password" for authentication. Just wondering, I guess if this sends passwords in plain text.
