Cloudron Forum

+1 for this feature. Especially, that zen.spamhaus.org, the default mail DNSBL used by Cloudron has a very harsh policy with ipv6 email. If one IP on a /64 ipv6 range is blacklisted, all the IP in that range get blacklisted :S.

Hi @girish ,
I see, it seems to be that indeed. The server runs on Upcloud actually.
I will try one of the solution you propose.

Many thanks for your help,

Hello there,
In the email status of the cloudron email menu, the smtp status failed for "Outbound SMTP" with the following error:

Connect to smtp.gmail.com timed out. Check if port 25 (outbound) is blocked

The port is open in my machine. Further, the email logs give those message :

I've also follow the guide to setup the DNS record...
Beyond that everithing is working, app are running...

Any idea of what I can try to get the outbound mail working ?

Thanks,
