Word Filter Private Mails / block, unblock Mails

[muffel]

Hello,

we have the problem in our forum, that there are many users who send spam to other users. I know, that there is a word filter for the global forum, that also works for private mails.

But is there any mod, for only private mails, to have the possibilty to filter some words out of Private Mails, or / and to filter als eMails or links in private mails, maybe with a regular expression?

One step further will be, that I want to have the function, that there is a filter of words, and when one Private Mail contains one of the word in the filter-list, then it will be blocked, admins get an eMail and can check and change the private mail before it can then be unblocked and sended normally.

Does anyone know, if there are some plugins / mods who can help me to do this?

Thank you!
