Normally you would have a system like mail marshal or symantec on premise that would do that.<br />
<br />
Not sure if Mimecast offers that service but you can let setup polices for email etc.

I ended up using my SonicWall Email Security device to create a whitelist. &nbsp;Any name to the specified user that wasn't on the whitelist had a customer header added. &nbsp;The SonicWall delivered all messages to my Communigate Pro Email Server, which had rules that processed mail and sent notifications based upon the header added by the SonicWall<br />
<br />
Thanks.

The user has a brand-new email account, and wants to control what senders they receive email from. <br />
They have an Exchange account with Intermedia, a large hosting company.<br />
<br />
I recall there being a company that had a system which receives and holds the email, notifies the user, and waits for the user to approve senders.<br />
<br />
Can anyone tell me what companies offer this service?

User only wants to receive email from senders they approve of.  Need a system that holds mail and notifies user

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

AntiSpam

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.
