Hi all, I know this is not really the forum for questions about Postfix but I thought I would try anyway. I am trying to set up a Postfix mail server to take the place of good old MS Exchange Server. If I can get it working I can offer a Linux / Postfix solution instead of Win NT/2K and MS Exchange. I have no problem sending and receiving mail to and from the Linux workstations. I can send from the windows 2k/98/ME using MS Outlook to all of the linux boxes but I cannot get a reply from them back to the Windows boxes. I only have POP3 incoming mail options in Outlook. I think that this is my problem. How do I enable MS Outlook to receive from the Linux mailserver. I cannot see any other option in the Outlook setup. If anyone is using this setup I would appreciate some pointers and references to docs or a website. Regards and thanks in advance, Keith Gibbons, Ireland
