Hi, I've tried goggle and the howtos but all I have managed to do is get confused. What I am trying to do is setup a mail server that can handle up to about 20/25 users, some on my network and some external. Currently most are managed using mercury under W2k, but I would like to setup a dedicated mail server to do the job. The other factors are multiple domains and the need to support Webmail and as the users will be using Windows, a virus checker, spam suppression and I that am new to Fedora/ Linux. I have had a 'play' with postfix and that looks OK as a MTA, my real problem is what next? There are a number of howtos (and books) covering mail setups but I have not been able to find anything that discusses the relative merits of the different MTUs etc. For fear of starting a my MTU is better than yours argument, what is the best setup to support the above and where can I find documentation on how to set it up? Thanks Rob
