For those testing the new POP3/IMAP proxy, please switch your incoming mail server to beta.webmail.us
Tonight we set up a second Dovecot proxy and slapped a load balancer in front of it, in order to closer simulate how the new proxy system will be running when it goes live. We also set up a real SSL certificate for beta.webmail.us so that you stop getting those annoying security warnings.
Give it a try. Post your results as a comment to this blog, or email email@example.com. Be sure to mention what mail program you are using, as well as how you are connecting (POP3/IMAP, SSL/TLS/plain-text).
