For the record on FreeBSD systems! The use of DES/MD5 is controlled entirely by the crypt libraries. Vpopmail doesn't control the use of DES/MD5 passwords. If you dig through the source you can see that it sends the entire crypted password as the crypt key. ie.. crypt( 'joeblow',

Using stunnel: stunnel -d 995 -r localhost:pop3 -p /usr/local/etc/stunnel.pem Change the last argument to the path your private key/cert PEM file. Only downside is your pop3 logs now show the logins from 127.0.0.1. Ken Jones writes: Thanks. I'm reading the url now. I think I confused
