Hi,

I've discovered a problem with my iRedMail-installation. Some clients (for example Maildroid) are trying to connect to the server via IPv6. I'm getting the follwing error message:

Could not connect to SMTP host: example.com, port: 587 (failed to connect to example.com/***IPv6-adress*** (port 587) after 30000ms: isConnected failed: ECONNREFUSED (Connection refused) (isConnected failed: ECONNREFUSED (Connection refused)))

What can I do to prevent this?

Re: IPv6 problems?

*) If you don't have IPv6 address, then you should ask you clients to use IPv4 address.
*) If you have IPv6, please check your firewall rules to make sure ports of mail services are open.
