You have ignored the OP's statement that he is a radio amateur, and that the FCC prohibits the use of encryption by radio amateurs. This is about ensuring that the spectrum that radio amateurs are licensed to use (a public resource) is not subverted for private purposes. Hams are supposed to be a largely self-policing community; encryption prevents that. As an individual radio amateur, the OP needs to ensure that he complies with the FCC rules if he wants to keep his license. If he cannot configure his SMTP server in a compliant manner he should not offer an SMTP-based service that transports messages across the ham frequencies.
