Postfix: User unknown in virtual alias table

Question

For some reason when I send an email from my self-hosted postfix server, it works, but can't receive due to this:

I'm trying to send a mail from [email protected] to [email protected], but doesn't work. However, as I said, it works the other way around. This is my postconf -n

Solution

1. 5.1.1 User unknown in virtual alias table

   • Check that your /etc/postfix/virtual has a virtual_alias_maps entry for [email protected], binding it to a local or foreign address, not to another virtual alias.
   • Remember to postmap /etc/postfix/virtual in order to update the corresponding .db, as you are using hash: type database.

2. 5.7.1 Service unavailable; Client host [190.100.12.50] blocked using pbl.spamhaus.org;

   • Self-documenting. Your IP is blocked using a DNS blacklist.
   • Avoid getting on such listings. For example, do not make your server an open relay using that relay_domains = * and apply suitable relay and access control. If you don't, you'll soon be blocked everywhere.

"Check that your /etc/postfix/virtual has a virtual_alias_maps entry for [email protected]" - But I want to send an email from that address to [email protected], because in that case I would have to add a thousand email addresses from ppl who tries to send me emails

Mixed them up. Corrected. The answer otherwise stays the same.
