Thanks for the answer Fritz.

I just want to highlight this: as far as I see, if TLS proxy is enabled,
then when a client sends an email, the auto-whitelist feature cannot be used
(since communication is unreadable for ASSP). That would be a serious
problem for be, that's why I'll configure "do TLS".
