Postfix not recieving or sending mail;

1

I am having this issue within Mail-in-a-Box and there is no error logs so I am quite confused…
|✖|Incoming Mail (SMTP/postfix) is running but is not publicly accessible at 1.1.1.1:25.| | --- | --- | |✖|Outgoing Mail (SMTP 465/postfix) is running but is not publicly accessible at 1.1.1.1:465.| |✖|Outgoing Mail (SMTP 587/postfix) is running but is not publicly accessible at 1.1.1.1:587.|

Probably the easiest thing to do here is re-run the setup script

curl -s https://mailinabox.email/setup.sh | sudo bash

If this doesn’t work or if you have already done this can you check the

/etc/mailinabox.conf

file and determine if your public IP is 1.1.1.1 ?

Might also want to check the

/etc/postfix/main.cf

This file should have a mynetworks = 127.0.0.0/8 [and your real public IP]

If you edit something you might want to restart postfix or just reboot the box.

service postfix restart

oh, also check

/etc/hosts

for your boxes name

 cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 mail

where my server is “mail.example.com” but mostly others set their stuff up like “box.example.com” so instead of mail above you might see/need “box”

Output of /etc/hosts

`

The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouter `

resolved via setup script
