### Describe your issue
Mail was working properly.
After a recent upgrade, mails started to bounce. “status=bounced (mail for XXX loops back to myself yunohost)”
Mails seem to go through rspamd wihtough being blocked, but they don’t arrive in the mail box.
It was all working a couple days ago.

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](http://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 :
```auto
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
127.0.0.1 domain
```

It says that my system has configured “manage\_etc\_hosts” as true.
from what I see, it’s more in the form of
```auto
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
