[webmin-l] Oddity with DNS zone records - Virtualmin GPL

[doug r. <do...@ar...>]

This is probably something I've misconfigured, but I can't figure it out.

I'm using latest versions of Webmin, Virtualmin and the Bind module, with Bind v. 9.2.4, 
on CentOS 4.5.

Originally, after setting everything up, I'd add a domain in Virtualmin and four A records 
would be created, e.g.:

example.com
ftp.example.com
mail.example.com
www.example.com

But now when I add a domain, I get a fifth A record:

m.example.com

I don't know when this 'm.' A record started being created, it's been going on for a few 
months at least -- I haven't been carefully reviewing the domain zone files.

Any ideas on what I've done to cause the automatic creation of this 'm.' A record when 
adding a domain in Virtualmin?

Thanks,

Doug
