can't receive email from a specific user

Questions have to be asked to narrow down the search;
* Can the recipient receive email from other users?
* Can others in the same domain receive email from the same sender (same email)?
* Has the recipient (or admin) set up rules that may be filtering mail from this sender?
* Has anything else on the network been done (eg addition of spam filtering) that could affect message flow.
* are there any logs available to you that might indicate what is going on.
* Does the sender receive any sort of bounce-back, or error message.

Good Luck!
