Watchguard SMTP Masquerading

In WatchGuard XTM SMTP Proxy definitions, it implies you can set up a rule for "masquerading".  However, how do you set up the replacement string?   For instance, if I want to be redirected to, it is easy enough to match the string and replace it.  But, if I want everyone to be redirected to their same name, how do you set up the replacement string?  You can use a wildcard on the string match but what syntax do they use for the replacement string to attach the portion before   Seems that this should be a simple process for creating masquerading.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This is configured in the proxy settings. Mail From and Rcpt To is where you configure it.

Thanks - I know WHERE to set up the rewrite... just could not get a valid replacement string.  For instance, if I use * in the Pattern Match (or Regular Expression) and the incoming address is, I could not find a replacement string that would give me  I tried the typical regular expression field information (like $` , etc.) to get the string preceding the but it appears the replacement field only allows literal characters.

If you don't switch to the advanced view it will handle the syntax for you. But this should replace the domain of the email address when in advanced view:
Pattern match: *
Replace action: \
