checkdnsrr for *.domanname.com gives "not found". It's okay.
It works for most domains in internet. But on my system 
checkdnsrr("*.7thGuard.net") and checkdnsrr("*.7thGuard.com") returns true. Should't it always return "fasle"?

When I used nslookup on your site I got...

> set type=MX (The default type that PHP looks for)

> 7thGuard.net

7thGuard.net
preference=10, mail exchanger = mail.7thGuard.net
[...]

> *.7thGuard.net

Name: *.7thGuard.net

*.7thGuard.net
preference=10, mail exchanger = mail.7thGuard.net
[...]

So, *.7thGuard.net has MX records.  By default, checkdnsrr
looks for MX records.  Not a PHP bug.

but, for example, checkdnsrr("*.7bulls.com") returns false. 7bulls.com also has MX.

no it doesn't

7bulls.com may have MX records, but no "*.7bulls.com"

nslookup on *.7bulls.com

> set type=MX

>*.7bulls.com

**207-230-75-222.deltacom.net can't find *.7bulls.com: Non-
existant host/domain
