I successfully got the script from this post to work:
PHP interface to DH Control Panel
But I also need to have forwarding-only addresses handled by a PHP script, as discussed here:
In the wiki it says “If you must have your own custom .procmailrc, you will only be able to set one up for mail accounts that are tied to shell/ftp accounts. You cannot access the .procmailrc file for mail accounts that use the autogenerated mXXXXXXX accounts.” http://wiki.dreamhost.com/Procmail
So is there any hope to have not just mXXXXXXX accounts, but forwarding-only addresses handled by a script? And if there’s hope (as Obama claims), how can I accomplish this?
