 This part really needs take care of bunch of IP
addresses. It does not look flexible to me.
ASAP, DCC does not handle regexp.Therefore, writing
*.yahoogroups.com as a whitelist entry doesn't work.

It does not seem to me possible,'cause our users's are
susbcribed to many groups on yahoo and other sites.
and they keep on subscibing to new groups oftenly.

Do you have any other idea about solving this problem

P.S. Have you got my mail about dcc+qmail integration
? I sent you it twice, but got no answer back.
