log files double rotate happening

[Lists]

Hi all,

I have set up in logrotate.conf the following (intent is to compress the 
maillog files weekly)
what is happening is that i'm getting zip files created ie maillog.1.gz 
but also getting the maillog.0 maillog.1 files being created.
It is making it quite difficult to find information in them later.

Can someone guide me to turn of the original maillog.0 maillog.1 
rotation (as i think the rotation in the below logrotate would suffice)

Thanks
Kate
