dovecot - Nov 2015 - dsync imapc authentication mechanisms

I'm trying to use dsync to mirror mail onto a remote IMAP server. 
The remote server is generating an error that authentication via 
plain text is not permitted.  Does dsync imapc support any 
non-clear-text authentication mechanisms?  The remote server supports:

AUTH=CRAM-MD5 AUTH=DIGEST-MD5 AUTH=NTLM

imapc supports SSL/TLS to avoid plaintext auth, but right now it can only
support LOGIN and PLAIN mechanisms. It could support others, but somebody would
just need to implement it to src/lib-sasl/. Afterwards you can use
imapc_sasl_mechanisms to set the wanted SASL mechanism.
