This TYPO3 extension was inspired by ameos_mailredirect, but allows a more flexible redirecting of adresses. E.g. if you use the postfix adress extension (tagging), you can generate addresses dynamically like mailtest+{local}-{domain}-{tld}@yourdomain.org.
All configuration takes place in the TYPO3 extension manager.
The redirect can be enabled for specific User-Agents and/or IPs. If you want to redirect all mails, set the configuration to * for both checks.
