E-mail across OpenVMS and RedHat 7.3 is included with the base distribution at no additional charge. OpenVMS adds some additional checking and testing of Open Source e-mail (seeing as it writes the TCP/IP stack and ports Mozilla to OpenVMS). Linux and OpenVMS can use the same standard tools to send e-mail, trade files, share disks, and browse each other's Web sites. E-mail is usually the first application to be established in a network then, knowing that works, the others are easy. Well, at least we know e-mail works.
