In any case where code 513 poped up from? Didn't find it in any smtp related rfcs any reference to this code.
In case it is made up - it is very reasonable for clients to abnormally abort whole smtp session when they receive unknown / illegal code. And in this case it's not clients problem.
Can you find any reference to code 513 anywhere? Please? So I can peacefully look for VALID email client that familiar with it?

And when remote servers start injecting crap messages into your mail server, you want to send DSN's for those, too? How many of those DSN's will be undeliverable? How large do you think the mail queue will get when they start stacking up?
Ignoring the SMTP spec is never the right thing to do. I'm not aware of any mail servers that will accept messages that they know will not be deliverable. Can you cite examples?
All other email-servers I've seen are accepting the adress, alltough one adress is wrong (and also if there is only one "rcpt to" and this one is wrong) then you get an error message back with "mail not deliverable" I'm not sending from a different smtp-server, I'm using the one from the server itself. When you use courier for the same it states the 513 error and the client aborts.
So basically, the question is, "Can you please open up a DoS attack method in Courier, like these other servers have? I'd like to help make the world a worse place, just because my email client isn't smart enough to know this is wrong." -- Imagine someone (a spammer or vindictive ex-user) deciding to send... oh say... 10-million emails with random mailbox names such as "alkag4eavea39av" and "awerrtuiav". You want to *accept* all those, and make your server work to send back 10-million DSN's?!?! Eesh!!
This sounds to me like something that should changed in a local copy of Courier, and just accept the risk of mail queue overload if it's important enough to you. -- Though I *highly* discourage even doing that!!
I certainly don't *believe* that Sam would think this is the right thing to do for Courier generally. (I hope not anyway!) And it certainly is just *asking* for trouble with your server, if you ask me.
