Please help with question "Client Debate"

There are many options in selecting and maintaining E-mail clients. Is there anyone that can please describe their experiences (if any) configuring Exchange and Sendmail and discuss why they would prefer one over another in a business setting. Thank you, so very much for any help that anyone can give.

Still need help with this question, the response that I got is not helpful, please help!

Can somebody at least explain the advantages and disadvantages of Exchange and Sendmail?

Is there another website anyone could refer me to? One that doesn't ask me for my credit card info, essentially a website that would help answer my question, minus the fee included.

So I guess the more appropriate question is which one, (in someone's personal opinion) is better in terms of maintaining E-mail clients in a business setting? Exchange or Sendmail?

i think gmail is better because its much quicker loading on my computer and maby urs. I would choose that also because most peple have a gmal and u can chat on it. hope I helped un like the other:)

Maybe this isn't the best place to ask. Try:
