Mailcow and dnsmasq on the same machine

Edgarsons

Hello,

Is it possible to use Mailcow and dnsmasq on the same machine?
For a while I received most of the new emails in Mailcow, but at some point all messages were delivered only to the old email provider. That was more or less about the same time I set up dnsmasq on the machine Mailcow is installed on to access self-hosted tools from the home network (my server computer is on the same network) so I guess that Mailcow and dnsmasq combination is the main reason why emails are not delivered to Mailcow anymore. In domain DNS settings MX record for the Mailcow email domain has the highest priority.
What can be done to receive new email messages in Mailcow again?

They don’t interfere each other. Unbond is used locally.

What could be the reason why emails are not delivered to Mailcow anymore? Should I create a new discussion about this problem?

Yes, would be a good idea to keep this separated. But in this case, check your postfix logs for incoming connections. If there aren’t any, it’s most likely network related from outside.

I created a new discussion here.

Is additional dnsmasq configuration needed for Mailcow if both are deployed on the same machine?
