<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">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:</p>
<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"><span style="font-family:DejaVu Sans;"><span style="color:#fcfcfc;"><span style="background-color:#141618;"><</span></span><a href="mailto:lancewillis2@cleanmaids.nyc">lancewillis2@cleanmaids.nyc</a><span style="color:#fcfcfc;">>: host mail10.mymailcheap.com[51.68.115.196] said:</span></span></p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"><span style="color:#fcfcfc;"><span style="background-color:#141618;"> 550 5.1.1 <</span></span><span style="color:#1d99f3;">lancewillis2@cleanmaids.nyc</span><span style="color:#fcfcfc;">>: Recipient address rejected:</span></p>
<p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;"><span style="color:#fcfcfc;"><span style="background-color:#141618;"> undeliverable address: host mail10.mymailcheap.com[private/dovecot-lmtp]</span></span></p>

<br /><p style="margin-top:0;margin-bottom:0;margin-left:0;margin-right:0;">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.</p>
