Thank you both for your input. &nbsp;I'm going to try to convince my client not to listen to their partner. &nbsp;They use GFI and only the one person suggesting this software gets a large amount of spam. &nbsp;I like to have complete control with spam blocking. &nbsp;I checked with Sendio and it seems like you purchase a piece of hardware that does all the SAV.

I was wondering if anybody had any input on SAV. &nbsp;A client of mine has a partner that uses this. &nbsp;When you send an email to the company behind a SAV it sends an email back to you asking for you to reply to be added to the whitelist. &nbsp;It seems to help with a lot of SPAM.<br />

Sender Address Verification Applications

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.

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

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.
