Cloudron Forum

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.

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!

All Cool I hand\t connected the app of listmonk through the cloudron app manager

Does anybody know why this happens ? or how to get around it ?

Does anyone know how to properly connect cloudron with listmonk ?
What I want to achieve is to be able to properly set an unsubscribe link for my email campaigns.
Currently it doesn't redirect to mailing preferences page.
it only displays " You are seeing this page because the DNS record of mail.poisonbrainbeats.com is set to this server's IP but Cloudron has no app configured for this domain. "

There it is !
it worked! Created a Type A DNS record for my.poisonbrainbeats.com needs to point to my IP address [IPV4]
DId the same for a Type AAAA DNS record for my.poisonbrainbeats.com that points to my IPV6 address.
