[Dovecot] Curious problem: Plaintext authentication disallowed on non-secure (SSL/TLS) [read: all] connections.

Hello all,

I've set up a new instance of dovecot 2.0.9 to use as a POP3/IMAP proxy. On trying to login I am told '-ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections'.

I have set 'disable_plaintext_auth = no' (see output of doveconf attached). More curious still is that *this happens for SSL connections too*.

Something seems very wrong here.
