Unable to recieve emails

Unable to recieve emails

Hi - I know this question has been asked before, but none seem to answer the question I'm after and I have come to the end of the road!!

I can send emails but not receive them. Have implemented all the amendments (correctly I think) on our server, but it still does not work. 

Also, is there any way to also receive the emails locally on desktop (Outlook express).

Many thanks.
