Question secure mail.[domainname].xx with SSL

[Albertje]

Hello,

i see a lot of possibilities of automatic installing email and so on. This is ok but what i do not understand is that mail will not be secured. But when you use automatic installing mail then it is always adding the incoming and outgoing mailaservers with mail.domain.com This gives problems with certificate.
In this case i have to enable wildcard to secure mail.

But if i use this i cannot automatic renew it while customers uses not the DNS from plesk but extern.

I think if let's encrypt give you the possibility to secure mail to then everything will alway be secured.

so not only imap, pop, smtp but also mail

so i hope it is possible to add mail into the secure list in let's encrypt.

regards Albert
