Thanks for the response, I'm certain now it has nothing to do with K-9, and everything to do with my hosting company: they say they can't investigate as nothing hits their logs, yet they won't say whether they are using SSL v3 or TLS >= v1. They also say no-one else has reported this to them. I'm stuck. Looks like my only option - if I want to have secure email - is to switch hosting company - and that's going to be painful.
