SlashTCO.com: Mailserver solutions - Open Source vs ProprietaryMar 04, 2001, 14:13 (12 Talkback[s])

"Like most things, Microsoft's Exchange mail server has its advocates and its critics. For those who fall into the latter category, one alternative is to run a Linux/Open Source mailserver. The most obvious advantage of doing this is the cost savings involved; an Exchange server software with 5 Client Access Licences (CALs) will cost 879.35 + hardware costs, whereas the cost of an Open Source mailserver solution amounts to the value of the hardware upon which it runs."
"Current users of Exchange may concede the point when the cost argument is raised, but their next questions will invariably be "Can Open Source mailservers do what Exchange can?" and "Are they scalable?"
"There are many functions provided by Exchange that are not available with Open Source mailservers, one example of which is the groupware functionality. Although efforts are being made in this area, the Open Source world does not currently provide an alternative that offers the same level of usability, integration and functionality as Lotus and Microsoft. Therefore, if a company requires a mailserver with groupware functionality, Lotus Notes or MS Exchange - whilst costly - would probably be the best solution."
