What operating system would be suitable for a mail server of an organization having 1000 email accounts?

Answer

FreeBSD, available for free download from http://www.freebsd.org/. FreeBSD powers a number of commercial web and mail hosting sites, including many of the servers at Yahoo! FreeBSD supports a number of popular mail servers, including sendmail, postfix, exim, and qmail, plus spam and virus filters, IMAP and POP servers for client access to mail, and any other email related utilities your heart may desire.

A tutorial on how to create a mail server running FreeBSD, sendmail, and the University of Washington POP and IMAP server is available at:

Answer:

Any server intended operating system: NT4, 2000 Server, 2003 Server, 2008 Server, OS/X, Linux, FreeBSD, NetBSD. The hard part about servers is matching the load (amount of work), the hardware (as low cost as possible yet still accomplish the goal), and the operating system (cost, ease of administration, stability and security) against your needs now and for a specific period of time into the future: a year, 2 years, 5 years. That's what infrastructure engineers do - they optimize the use of machines against load and future use.

The best system to use is one that whomever is administering the system knows - you can have the best op system and if the admin can't use it right (not experienced with it) you might as well open your windows and doors to the world "come on in, get our data!" or go the users and say "sorry, the server will be going down all the time randomly, expect it."
