Add kinghost.net and uni5.net

[andreluiscastillo]

KingHost (https://king.host) is a Brazilian hosting provider. Customer domains
hosted with us use MX records under kinghost.net (direct customers, e.g.
mx-vip-01.kinghost.net) or uni5.net (reseller network, e.g. mx-vip-01.uni5.net),
so these entries are meant to be matched through the MX lookup.

Settings (identical for both networks, hostnames differ):

• IMAP: imap.:993 SSL, username = full e-mail address
• SMTP: smtp.:465 SSL, username = full e-mail address

Both hosts present valid public TLS certificates. We also serve the same data
at https://autoconfig.kinghost.net/mail/config-v1.1.xml?emailaddress=

.

Hi @andreluiscastillo, thanks for your PR!

As explained in our documentation, clients like Thunderbird should be able to find autoconfig files by using the value of the MX record as a base. Following your example, hosting autoconfig files at https://autoconfig.kinghost.net/mail/config-v1.1.xml (which you already do) and https://autoconfig.uni5.net/mail/config-v1.1.xml should be enough, without needing an entry in ISPDB.

Is there a specific reason why this setup wouldn't work for you?
