SMTP Addresses Tab: Swap Proxy

When syncing LDAP directories, you have the option to manipulate proxyaddress, swapping a secondary smtp up to be the primary *SMTP**.

Typically an Exchange mailbox is given a primary SMTP address. This address is the user’s reply-to address. Secondary smtp addresses can be added that allow the user to receive email using other addresses.

UnitySync’s Swap Proxy function reads through the proxyaddresses using a rule-set. If a match occurs, that address becomes the primary address and the old primary address is pushed into the proxy list.

The swapping logic looks like this:

• Read the domain part of each proxy addresses and compare, in order, against those you have supplied in the Swap Proxy parameter.

• When a match is found:

  • Swap the matching secondary smtp proxyaddress, making it the Primary SMTP address.
    AND
  • Swap the original Primary SMTP address making it a secondary smtp proxyaddresses

Note, when a Swap takes place, mail and targetaddress are also set using the swapped address.

Example of Standard Swap Proxy Usage

Assume the following three records exist on your Source.

SMTP:jsmith@aol.com
smtp:james@zoomit.com
smtp:support@p.com
smtp:jim@home.com

SMTP:tsmith@aol.com
smtp:tom@zoomit.com
smtp:tommy@home.com

SMTP:bubba@slow.net
smtp:Charles@fast.net

On the ProxyAddresses tab, the Swap Proxy field is set to:

• @p.com,@home.com

When a match is found:

• Swap the matching smtp, making it the primary SMTP address.

Resulting three Destination Records:

SMTP: support@p.com
smtp:james@zoomit.com
smtp:jsmith@aol.com
smtp:jim@home.com

SMTP:tommy@home.com
smtp:tom@zoomit.com
smtp:tsmith@aol.com

SMTP:bubba@slow.net
smtp:Charles@fast.net (nothing is swapped)

Notes 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 SwapProxy of simply XYZ.com, then both smtp addresses above 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 rule-set:

• The order of the swap proxy list sets the order of the search through the secondary addresses.
• The swap proxy list is done by subtring matching (no wildcards should be used)
• If a proxy is not matched the addresses are left alone.
• UnitySync will use the first proxy it matches.
