- gumby 6y agoIn this case you’re right. I really doubt someone is probing the RCPT TO response to decide if a server is legit or not! Certainly there are protocols where you might be required to accept an option or configuration value you can’t implement and so simply discard it. Perhaps some QoS request for example. Or termcap info for cursor movement when all you do is act like you’re talking to a printing terminal.
- technion 6y agoIn this case there actually is a benefit. I've seen issues where people weren't able to communicate with customers because someone's running a mail server that rejects email based on the RFC-Clueless RBL or its predecessor, RFC-Ignorant[0]. I've never in history seen postmaster@domain every receive anything but spam, and I have seen it receive so much spam that I would never identify a legitimate email amongst the screens full of junk if one ever did arrive.
