when i run update command i am getting error

for installation steps i reffred link:-http://www.server-world.info/en/note?os=CentOS_5&p=mail&f=9

command wt i typed:-/usr/share/awstats/wwwroot/cgi-bin/awstats.pl -config=mail.mydomain.com. -update





Error: Couldn't open config file "awstats.mail.mydomain.com.conf.conf" nor "awstats.conf" after searching in path "/usr/share/awstats/wwwroot/cgi-bin,/etc/awstats,/usr/local/etc/awstats,/etc,/etc/opt/awstats": No such file or directory

- Did you use correct config parameter ?
Example: If your config file is awstats.mysite.conf, use -config=mysite
- Did you create your config file 'awstats.mail.mydomain.com.conf.conf' ?
If not, you can run "awstats_configure.pl"
from command line, or create it manually.

Check config file, permissions and AWStats documentation (in 'docs' directory).

Did you replaced mydomain with your domain . I mean to say do mydomain exist or your mail server having diffrent domain name .

Thanks

while installation only i replaced to my actually domain name
