you are making it hard to impossible to help you if you are mixing servers and their responses and port 993 will *never ever* show STARTTLS because it is IMAPS which enforces a encrypted connection and *not* STARTTLS where the inital connection is unencrpyted by design so *please* stay at *one* config, *one* machine and *one* port for debugging if the machine in question announces STARTTLS on port 143 it should work and that is why i asked if *a different client* than a iPhone is using STARTTLS on *that* machine with *that config*
