[bug]: Suggested DNS records incorrectly include subdomain name only

[jeanas]

What happened?

I'm using the latest version of Stalwart installed today. The zonefile generated in the admin Web interface contained records like this:

@                  IN MX    10 mail-server.
mail               IN CNAME mail-server.
_jmap._tcp         IN SRV   0 1 443 mail-server.
_imaps._tcp        IN SRV   0 1 993 mail-server.
_imap._tcp         IN SRV   0 1 143 mail-server.
_pop3s._tcp        IN SRV   0 1 995 mail-server.
_pop3._tcp         IN SRV   0 1 110 mail-server.
_submissions._tcp  IN SRV   0 1 465 mail-server.
_submission._tcp   IN SRV   0 1 587 mail-server.
autoconfig         IN CNAME mail-server.
autodiscover       IN CNAME mail-server.

which I believe is incorrect: it should be ... mail-server.my-domain.tld each time. (Took me a while to debug…)

How can we reproduce the problem?

I can reproduce the problem by doing the following steps:

• Install Stalwart
• Add a domain in admin interface
• Observe generated DNS records

The value used here is lookup.default.hostname (webadmin: Settings > Server > Network > Hostname), if the default value is incorrect for some reason, you should change it

(You should also configure lookup.default.domain in Settings > SMTP > Reporting > Default Domain which is empty by default for some reason)

[mdecimus]

As @andreymal said, you need to update your server hostname in the Stalwart configuration.

Thanks, and sorry for the noise.
