replace MS Exchange with SendMail?

[cahelmster]

I am running MS Exchange Server for interoffice and Internet email and would like to move completely away from Exchange and setup SendMail for Linux. I'm using Outlook 2000 on all PCs. My questions are...how easy is it to setup and administer SendMail, what distribution of Linux should I use, how will SendMail fit into an NT/2000 network, and how will Outlook 2000 work with it?

Thanks for all responses!

Well, that is a tall order! I guess my question first would be do you need full MS Exchange functionality? In other words, Tasks, Calander, Global Address Book, Public Folders and such? If so then Sendmail will not do it for you. Sendmail is only an email server, SMTP and POP; I am not sure but I do not think it can handle IMAP - but I could be wrong. If you are looking to repalce Exchange look at this product -

It is not a free product though, but it is a lot cheaper than Exchange.

Hes right, exchange is there for a reason, and sendmail is not a replacement for it . Sendmail is a powerfull mail server though, exchange has more worker - company applications and collaberation. Many organizations will use an NT / 2000 network, and have outlook connect to exchange 5.5 -2k, for employees to use all of exchange and outlooks integration. , but they dont trust microsoft security, so they put redundant sendmail servers at the forefront of the network, the exchanges servers merely are internal mail, and internal application servers, that forward outbound mail to the sendmail, and rec mail for abc.com company inbound.. otherwise to use outlook u can only use the pop smtp, outlook may have problems with reg connections..

or if u are a smaller org , keep exch internal , use sendmail for ext, but give sec mx rec to exchange for failover if 1 server goes down. i used sendmail at our hosting site with mx =10, it would forward accross town to our HQ exch server , which had MX =20, and would que the mail if it could not connact exchange, worked great for our budget plan to have redunant mail , with 2 different networks
