Letsencrypt and Webmail, Exim and Dovecot

[hci]

Is there a simple howto for getting Letsencrypt to work on Centos with Webmail, Exim and Dovecot?

There seems to be no mention of email services there?

I want www.my-3rd-domain.com to support SSL and mail.my-3rd-domain.com to also support it with HTTP, IMAP, POP3 and SMTP.

Hello,

By default whether or not you use Let's Encrypt on a directadmin server, only one cert gets installed into exim/dovecot and it the server-wide cert usually issued for hostname. If you need other certs for exim and dovecot you can currently install them manually either by using SNI feature or per IP bases.

and of cause you might consider searching the forums for similar threads.

Would it be simpler to just purchase a wildcard SSL certificate for my primary domain and use if for /webmail and email?

I am simply having a lot of problems with smartphones etc not liking not having signed SSL.

You can use either hostname SSL cert to connect to IMAP, SMTP, POP3, HTTPS (including webmails) or wildcard with your domain, for example if your hostname is server.company.com, and you have a wildcard for *.company.com then it's fine.
