So what's going wrong with TLS? In some other mailers it's interpreted as not just selection of ciphers, but SSL means fall back to unencrypted if you can't set it up, while TLS means mandatory, which is what I want. Does anyone know what SSL vs. TLS really means in SOGo?
SSL means beginning SSL negotiation directly after having handshaked the TCP connection. The standard port for IMAP over SSL is 993.
TLS means the usage of STARTTLS to raise a normal (unencrypted) connection to an encrypted one using an (in the IMAP case) IMAP command (STARTTLS). It just uses the normal IMAP port 143.
Your external server does not seem to accept STARTTLS on port 143, so with the "SSL" setting you use the port 993 of the external mail server which just works fine.
