I am running Virtualmin Pro on CentOS 6.3 x64 and have a successful installation set up that is serving several Web hosting customers.
Lately though some customers have been complaining that their "webmail.domain.tld" addresses are not working, and upon a bit of investigation today I found that this is because these DNS entries do not exist. This means that apparently an entry for "webmail.domain.tld" is not being created when a new virtual host is set up.
I haven't found any settings in the GUI, specifically under "Server Templates", that would control the automatic creation of this DNS entry.
How can I resolve this apparent problem and enable the creation of "webmail.domain.tld"?
Thanks for any assistance provided.
