STARTTLS check for SMTP servers
Ath the moment SMTP ports may be checked for responsiveness but not for valid connections. Interesting would be:
- check if there is really a SMTP server
- check for STARTTLS
- check for valid certificate / expiring certificate
- check for MTA-STS/DANE

It would be nice to be able to check the IMAP protocol as well.

This is the one piece missing for us as we are looking to test for SSL certficates everywhere and UpDownio does not yet do this with SMTP servers. Its a slightly different test because you have to connect and do a STARTLS but it really would help to have this type of check included in the monitoring.
