There ain't no way the MTA can reliably predict an invalid address for other hosts/domains/machines. That's not how email works. :-) It's *possible* that a well-constructed MTA could maybe be configured to "know" that 'dude' is not a local user, alias, nor otherwise valid recipient, and that MTA could perhaps be configured to return an error in that case. But there isn't a whole lot PHP can "do" about this either way -- If your MTA isn't doing what you want it to do (return error for 'dude') then you'll need to focus your efforts on the MTA, completely independent of PHP. If you can get the MTA to complain right away on the command line that 'dude' is an invalid recipient, fire up PHP and test again. If all you get is a bounced email, then PHP ain't gonna magically do any better than that. To put it another way: PHP just spits out the answer the MTA gave it. If you don't like the answer, change the MTA. :-) You now have the joy of diving into sendmail documentation.
