I used to be stmp over SSL (ssmtp), published by IANA in 1997 I used (configured) it in the 2000's although it was already deprecated by IANA for a few years (in 1998). I retired it last year as rfc8314 was planned to replace it by submission over TLS. I did got a mail (spam) on it every few days though.
