[image] ndx1905-github: status=bounced Do you have ports 53 or 5353 open?

It wasn’t open… which is weird because it was working before. I opened 53 and 5353 (ingress only, should I do egress too?) Tried to send an email from outside to my mailbox and it bounced. Remote Server returned ‘554 5.4.6 < #5.4.6 X-Postfix; mail for xx.xx.net loops back to myself>’

I didn’t tell you to open them. They should be closed

Let regen the dnsmasq config with yunohost tools regen-conf --force, then check /etc/hosts for anything abnormal : cat /etc/hosts 127.0.0.1 localhost ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters 127.0.1.1 domain.com domain 127…

It says that my system has configured “manage_etc_hosts” as true. from what I see, it’s more in the form of 127.0.1.1 domain.com domain.com 127.0.0.1 domain.com domain.com

A bug has been identified in our postfix conf and should be fixed in 12.1.26, maybe that’s the cause of your issue, it’s a bit unclear what were the implications of the bug

Mails bounce or disappear. Suddenly can't receive mails anymore (was working before)
