I've just installed ZDC 7.1.4 and find it very nice. However I've got trouble understanding how I configure the client to use TLS when sending mails (using the starttls command).
I can only see that I can setup SSL in the SMTP sections when setting up my IMAP account. I need to use TLS and not SSL to be able to get everything dandy.

Also, is it possible to get the client not to check the certificates, it wouldn't allow me to setup an account without using a proper CA signed certificate.
