Multiple [my-list] marks

[Jacek <jacek @ oi . idl . krakow . pl>]

Is there any way I can filter subjects of the messages sent to the list so
that I get rid of multiple "[my-list]" marks and "Re: Re: Re:" ocurrences
in subject line?
I simply want to avoid messages with subjects such as: "[my-list]
Re: Re: [my-list] SomeTopic" etc.
Has anyone already come through this problem or do I have to append some
perl lines to original files?
