I've seen that on my instance as well yeah, using email addresses where there is a mail server 
running, but the accounts are not registered there so it gets rejected. One example I have of 
that is below:

<[email protected][1]>: host mail10.mymailcheap.com[51.68.115.196] said:
    550 5.1.1 <[email protected]>: Recipient address rejected:
    undeliverable address: host mail10.mymailcheap.com[private/dovecot-lmtp]
    said: 550 5.1.1 <[email protected]> User doesn't exist:
    [email protected] (in reply to RCPT TO command) (in reply to RCPT
    TO command)

I was wondering if I could take care of that by routing those domains back into my mail servers 
using DNS RPZ, and then configuring Postfix/Dovecot to catch-all to the round file. Didn't go 
anywhere so far, but might be a viable option.
