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. -- [Met vriendelijke groet] [Best regards] [Michael De Roover] --- --- --- --- [Mail] [*@nixmagic.com] [michael@[email protected]] [Web] [https://michael.de.roover.eu.org] [Forge] [https://git.nixmagic.com] [Weather] [Antwerpen] [22:00] [13.3°C] --- --- --- --- [0] [2025-10-31 22:51 CET] [~] [[email protected]] [$] [/usr/bin/sign-mail] [>_] --- --- --- --- -------- [1] mailto:[email protected]
