A certificate for mail.<domain>, installed into
Postfix (SMTP) and Dovecot (IMAP/POP3).
mail.<domain> must already have an A record pointing at
this server, and port 80 must be open, because validation happens over
HTTP. Postfix and Dovecot are reloaded afterwards; existing sessions are
not dropped. Let's Encrypt allows {{ duplicateLimit }} duplicate
certificates per registered domain per week, so avoid re-issuing a
healthy certificate.
One certificate per domain that sends or receives mail here.
Create a website before issuing a mail certificate for it.
