SSL support for SMTP and IMAP for mail.somedomain.com

[myVesta]

For now, myVesta support exim/dovecot SSL only for server hostname.
Next big update will be support for subdomains and for other domains (HestiaCP already has support for it).

What you can do now is to (as admin)

• go to WEB -> Edit (edit yourhostname)
• add mail.somedomain.com as Alias
• Save it
• On the same page turn off LetsEncrypt, and Save it
• On the same page turn on LetsEncrypt, and Save it

It will regenerate SSL for your hostname, and that SSL will also be valid for mail.somedomain.com, so you can use it as IMAP and SMTP hostname.
