Are you sure this is not a misunderstanding? When you host user accounts, on a tight, default, setup of OpenBSD (or any other OS), and allow them to ftp into their web-directories, how could one prevent them from uploading code that mail()-s something? Aside of removing mini_sendmail, that is. > Sure, if you go through and find every line of code where mail() is called, > you can add logging at that point.

If you host, for example, any CMS, it should have the functionality to the remote user, registered with that CMS, to request a password reset. Which SMTP+AUTH do you want to use here?? AFAICS, here we need to allow a straightforward SMTP. The userbase is registered in the various databases of the CMSes. And again, no sysadmin will re-write all user-supplied applications to extract all those remote users for SMTP-authentication.

Yes, this is the crucial point. I'd be more than happy to learn how to set this, for example in php.ini!

So, how to solve the problem, then?? Thanks anyway, Uwe
