I am learning (trying) to build my own mail server in Centos 7 VM. I have come to a problem when my incoming mails are getting rejected. Using POSTFIX I am trying to send emails from gmail to my mail but it is stucked by this error. Below I will provide as much information as I can. Btw I dont have any DNS record so I am using IP only. User is John.
[root@mail ~]# cat /etc/aliases
john: john

Any help will be appreciated :) Thank you.

Solution has been found:
/etc/postfix/main.cf
local_recipient_maps =
Local recipient maps is enabled by DEFAULT = setting that to empty enables postfix to finally accept message and store it in users file. Also to enable download email to users Outlook - set Chown permissions to the name of the user - e.g. chown john:john /var/spool/mail/john
Also to completely provide solution - change mynetworks = all ... to your home / local subnet ... e.g. my is 192.168.0.0/24
I found something like:
With regular expression tables, Postfix only queries with the full recipient address, and not with the bare username or the "@domain.tld" wild-card.
Let me know if that was helpful ;)
