This is primarily used if the source and destination servers are Exchange.
Typically an Exchange mailbox is given a primary smtp address. This address is the user’s reply-to address. Secondary (Proxy) addresses can be added that allow the user to receive email using other addresses.

UnitySync’s swap proxy function reads through the Proxy addresses using a ruleset. If a match occurs that address becomes the primary address and the old primary address is pushed into the proxy list.

For Example:

Source records:
Primary: jsmith@aol.com
Secondary: james@zoomit.com,support@p.com,jim@home.com
Primary: tsmith@aol.com
Secondary: tom@zoomit.com, tommy@home.com
Primary: bubba@slow.net
Secondary: Charles@fast.net

Swap proxy field is set to:   @p.com,@home.com

Results:
Primary: support@p.com
Secondary: james@zoomit.com,jsmith@aol.com,jim@home.com
Primary: tommy@home.com
Secondary: tom@zoomit.com, tsmith@aol.com
Primary: bubba@slow.net
Secondary: Charles@fast.net

A Note about Swap Proxy  Syntax:

It may or may not be necessary to include the @ prefix in the Swap Proxy domains you specify.  An example of when it is necessary is if you have two incoming domains that look like this:

EricN@DomainXYZ.com
Eric@XYZ.com

If you specify a Drop Proxy of simply XYZ.com, then both objects qualify for swapping. Which ever is returned first will be swapped to the primary.  If you specifically want the @XYZ.com domain to be primary, then you need to specify the Swap Proxy value as   @XYZ.com.

There are some guidelines to the ruleset:
