R: Use of Hostis Method to Determine Sender

[Marcello Marangio]

Hi
I made (after a suggestion in this ML, of course...) a similar thing with
the recipients:


MimeMessage msg = mail.getMessage();
Iterator itera = mail.getRecipients().iterator();
while(itera.hasNext()){
    MailAddress recip = (MailAddress)itera.next();
    if(mc.isLocalServer(recip.getHost()) ){
        // here we are sure that the recipient's server is actually my
server
        if(mc.isLocalUser(recip.getUser())){
                // here you are sure that the user does exist on my server
        } else {
            // ERROR:the user does not exist
        }
    } else {
       // not my cup of tea...
    }
}

how about a thing like that?

Ciao
Marcello
