[solved] Security Problem detected

[MicCo]

Hmmm, if I got it right,

- then what you are saying is that one of more users on an server can make an catcall e-mail address, and then recive e-mails from other users account ! ?.

This will be an very serious security issue, I will have serious problems as lots of my users are medical companies, dealing with a lot of money, so if an e-mail can be snapped by others, then the hosting ain't secure and an host can get in rearl trouble.
