IMAPS handshake failure

I am trying to configure e-mail on NSD 7.0.3 appliance. Our mail server is Lotus Domino 9.0.1 and it supports imaps protocol. A mailbox has been created for NSD and I can successfully connect to it using Thunderbird. I can also connect by using "openssl s_client" from the command line of NSD appliance. But when I configure relevant fields in NSD:

Incoming server: ourserver.ourdomain.com
Protocol: IMAPS
Port: <blank>
Username: ServiceDesk
Password: <correct_password>

...and press Test, I receive an error message:

Error connecting to host: Server chose SSLv3, but that protocol version is not enabled or not supported by the client.

(I ran tcpdump on the appliance while pressing Test, and the dump output shows NSD server connecting to IMAP server on port 993, IMAP server sending back the certificate and then NSD server responding with "Handshake failure".

IMAP server admin has enabled the use of SSLv2 on server side, but that doesn't seem to change the situation.

Is there anything that we can do on NSD side to get this working? Obviously we could try using plain IMAP (port 143) with all the security impliactions, but we prefer the traffic to be encrypted.
