Hi all, i have a linux 7.1 professional edition installed on one of my intel based machine which is acting as a mailgateway for lotus r5.i am using procmail as mta . but the problem is i have to maintain two address book.one is on lotus server and one is on linux. is there any way to configure my linux machine to just pass mail to lotus r5 and let lotus do all distribution to their mailboxes. -- Warm Regards Tarique Ansari Executive - Customer Support --
