There is a problem with my mailserver(postfix+procmail+fetchmail +redhat 9.0).If a mail is sent to multiple recipients (ie:To,Cc,Bc) ,all the recipients will get multiple copies of same mail.The number of multiple copies is proportional to the number of addressee.There is no problem if there is only one recipient ,ie

only To).
I checked all the configuration files (ie .procmailrc,.fetchmailrc ),but all seems to be fine.The same configuration was working fine till the other day.What may have gone wrong?
Please help me to find a solution.
