Anything amanda like but amanda itself is missing from IANA, at
least it is not here either, and we also have a script. (I once
posted it, as below.)

submissions is a standard, RFC 8314:
3.3. Implicit TLS for SMTP Submission
When a TCP connection is established for the "submissions" service
(default port 465), a TLS handshake begins immediately. Clients MUST
implement the certificate validation mechanism described in
[RFC7817]. Once the TLS session is established, Message Submission
protocol data [RFC6409] is exchanged as TLS application data for the
remainder of the TCP connection. (Note: The "submissions" service
name is defined in Section 7.3 of this document and follows the usual
convention that the name of a service layered on top of Implicit TLS
consists of the name of the service as used without TLS, with an "s"
appended.)
