That sounds like a great topic! We are in the process of moving email off of VMS to two Linux sendmail machines. One will be an SMTP gateway that scans for viruses and spam (and other things) using MIMEDefang, SpamAssassin, F-prot, then hands it off to the second system. The 2nd machine is just the message store that will hold users mailboxes and will be the POP/IMAP server. They will be running Redhat Advanced Server in a cluster configuration connected to a Magnitude SAN, so either box can failover and take on the duties of the other. The last cool thing is we have 16,000 users and not one of them will be in /etc/passwd. All user info (passwd, shadow, group) will be stored in an ldap database (Novell eDirectory on linux) using padl's nss_ldap library. We have a prototype mostly working now, while we wait for the new hardware to arrive. It is very cool stuff... -Ray -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Ray DeJean http://www.r-a-y.org Systems Engineer Southeastern Louisiana University IBM Certified Specialist AIX Administration, AIX Support =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
