Incomplete DNS zone files (using create-domain.pl)

Hi everyone.

Using virtualmin on a single IP address server (say IP=1.2.3.4), I have a probleme when I try to batch domain creation with create-domain.pl :

Beginning server creation ..

[...]

Adding new DNS zone .. .. done

[...]

All done!

But when I look at the /etc/bind/foo.com.hosts file : $ttl 38400 @ IN SOA srv1.mydomain.com. root.srv1.mydomain.com. ( 1182960350 10800 3600 604800 38400 ) @ IN NS srv1.mydomain.com. foo.com. IN A www.foo.com. IN A ftp.foo.com. IN A m.foo.com. IN A mail.foo.com. IN A foo.com. IN MX 5 mail.foo.com.

If I try any ip-related option, either it gives me the same result, or it returns an error.

When I create a domain (bar.com) with the webmin interface, the /etc/bind/bar.com.hosts is correct : $ttl 38400 @ IN SOA srv1.mydomain.com. root.srv1.mydomain.com. ( 1182960350 10800 3600 604800 38400 ) @ IN NS srv1.mydomain.com. bar.com. IN A 1.2.3.4 www.bar.com. IN A 1.2.3.4 ftp.bar.com. IN A 1.2.3.4 m.bar.com. IN A 1.2.3.4 mail.bar.com. IN A 1.2.3.4 bar.com. IN MX 5 mail.bar.com.

Forums and on-line documentation are not very verbose about the create-domain.pl command, so I'm kind of stuck here. Does anybody have any idea of what I may have done wrong or what I may give a try (misconfiguration, environment needed, further reading, etc.) ?

Regards.
