With ConfirmEdit you can whitelist URLs that you don't want to require a CAPTCHA using the MediaWiki:captcha-addurl-whitelist page. However you can't just whitelist a specific domain without a spammer being able to exploit it by adding the domain somewhere else in the URL.
For example: if you add wikimedia\.org to whitelist the wikimedia.org domain,
will all be able to bypass the CAPTCHA.
You can add a boundary by using \bdomain\.com\b .
The generated regex wasn't properly anchored, so would match later in the URL than it should.
Fixed in r34932; also made it match both http and https.
