Remove smtp_tls_security_level exception for nauta.cu

Browse Source 
nauta.cu MX servers don't support STARTTLS
and we have maintained this exception to allow delivery to nauta.cu.
Since nauta.cu has blocked largest chatmail relay instances,
we can remove this exception.
Even if it works today for some chatmail servers,
they will likely be blocked once the number of users grows.
Even now users from nauta.cu cannot practically participate
in groups.
