Hi No master password isn't required for certification. That more an internal technical design for our Webmail application. My fall back design is to employ two different dovecot proxies but I suspect I run the risk of mailbox corruption as the director nodes won't be shared.> It's not really necessary with SSL.This is a good point I'd forgotten to consider. It would allow me to mix master + PLAIN and then isolated DIGEST-MD5 maybe in a different proxy. The practical world vs the theory.
