Email is not configured properly

[poisonbrain]

I got a notification on my cloudron account that read "Email is not configured properly "

When I opened it read:

"poisonbrainbeats.com

PTR DNS record (PTR) did not match.
Hostname: 74.48.163.80
Expected: my.poisonbrainbeats.com
Actual: mail.poisonbrainbeats.com
Relay error: Connect to port25check.cloudron.io timed out. Check if port 25 (outbound) is blocked

prodbypoisonbrain.com

PTR DNS record (PTR) did not match.
Hostname: 74.48.163.80

Actual: mail.poisonbrainbeats.com "

Does anyone know if this affects the effectiveness of sending cold emails ?

Also how do I Check if port 25 (outbound) is blocked ?

Any help would be deeply appreciated!

@poisonbrain Hi,

To be honest, I've been using Cloudron for over a year and this notification comes back every day. I never thought about the question. It's true that it would be more practical to be able to send emails with the applications automatically etc. But so far I have managed the users myself directly from Cloudron. So I won't have any answers to give you. I think there is someone on the forum who will be able to answer you.

I just wanted to answer your post to tell you to be careful. I don't really know what's going on on the forum, it's been a while since I've used it, but personally, when I put data on the forum, I try to anonymize them and remove all the information that could be directly linked to my infrastructure. So it includes domain names, machine IPs and other information that could be really confidential and that could lead to unknown people in my infrastructure.

And there you have directly copied the error message that Cloudron sent you and inside we have the link to your Cloudron panel and the IP of your machine. I don't know if it's a test machine or if in any case it doesn't bother you to post this on the forum but I would rather in doubt warn you.

You can put my.example.com instead of your real domain And for your IP you can put 00.00.00 As you feel it, we don't need this information to help you I hope you'll found the answer to your question, even me it could help me I will keep an eye on your thread so that if someone answers simply it could help me too.
