Answer

1) correct but in my opinion, this sounds better: The other day, I received an email from someone in Iraq.
2) It seems correct to me but I would rather say:  The email said that they were interested in our products for the "Iraq rebuilding " project.
3) So I sent them an email in return with my company's HP address where they can find all the information they need and I and asked them to provide further information about them and their requirements. 
4) There is nothing that makes me happier and excited than our products being used for the purpose of rebuilding a country, but at the same time I was a little skeptical about the opportunity.
