mail logg

Well it seems that one or more of my clients likes to basically, upload e-mails scripts, test them. Not really a problem considering I can tell what new scripts are uploaded that have mail commands in them but what I would like to do is basically force the mail command to grab the user name and domain and send it as them by default.

So now the e-mails wont be coming from nobody@server.ext but should be user@domain.ext.
I also want it to logg the e-mails sent and from what script exactly.
I stop the spam and such on the server through a different method but that will only stop incoming, outgoing gets directed to my mail account and fills it with unable to send e-mail(46,900+ e-mails to me last time). So I need to create a way to tell who is sending them so I can get rid of the spam, accusations are useless and insulting, Id like to know EXACTLY, Id also like to logg who is logged into the ftp and what all their moves are, commands will suffise.

I am doing the best I can to keep the server from being used as a tool by malicious hackers and forgetfull/fresh clients.

I hope someone here can help, Thanks alot.

 

I guess Im trying to bump this.

Hope someone can help or point me in the right direction.
