I used to use SSMTP as a simple mail transport but got deprecated and so I moved to MSMTP. MSMTP now appears to have been removed in Leap 15.3 - I did the upgrade and the package was uninstalled and no longer seems to be available>:).
Any ideas or am I am going to have to go and do a full setup with Postfix which is massive overkill for what I really want which is to simply send out email status messages.
