You really want to apply it to both.
Otherwise, it's impossible to do a loopback test from your own long
that same long address to verify that the MTA in fact doesn't choke.
I didn't know that. Thanks for pointing it out.
There's also the part where there's an assumption that the recipient's MTA
send a bounce message to the MAIL FROM - which means your inbound RCPT TO:
to be able to accept the long address as well.
Makes sense. I'll include this part in my next version.
Thanks for the feedback. Really appreciate it.
