let´sencrypt mail server

with a fresh install of IspConfig 3.2 I can´t use a valid cert on my email server
take a look at this

My site have let´sencrypt and my domain alias too. Any idea to solve this issue?

 

ISPConfig only generate certs for web domains.
The only mail SSL cert is for server hostname itself.
In order to set accounts in mail clients with SSL you have to use server hostname instead of mail.domain.com as inbound and outbound server.

PD. Creo que somos paisanos

 

ok, thanks I´ll try it.
