So, I have gone ahead and added all of the proper DNS records, and then my mailserver which is mail.muneeb.co is not working. I have added the DKIM/SPF and DMARC records. I have also added a PTR (Reverse DNS Record as well). **Cloudflare DNS Records** [upl-image-preview url=https://community.mailcow.email/assets/files/2022-07-22/1658494985-353668-dns-record.png] So, whenever I send to my mailbox at muneeb@muneeb.co it receives the mail within a few seconds, but when I send mail using mail.muneeb.co/sogo it doesn't send the email forward. So, that's the dilemma.

Also, here is the DNS Tab in Configuration Tab where I have added my domain properly, I am hosting using AWS and I think I have set up my outbound and inbound rules properly. **DNS Section Mailcow UI** [upl-image-preview url=https://community.mailcow.email/assets/files/2022-07-22/1658495436-907014-image.png] **UFW Inbound Rules** [upl-image-preview url=https://community.mailcow.email/assets/files/2022-07-22/1658495315-98209-image.png] ** AWS Outbound Rules ** [upl-image-preview url=https://community.mailcow.email/assets/files/2022-07-22/1658495487-299603-image.png] **IMPORTANT NOTE** When I was installing mailcow-dockerized it gave me some errors about the docker config file that it automatically generated I was at version 1.29.1 of docker-compose at that point. So, then I did ``sudo ./update.sh`` and it automatically downloaded a lot of containers and ran mailcow (fine automatically), from where on I set everything up.

# Elastic IP even has Telnet Running [upl-image-preview url=https://community.mailcow.email/assets/files/2022-07-22/1658496978-429558-image.png]

**SOLUTION** SIGN UP TO SENDINBLUE AND USE Relay host and set it for your domain.

I have properly set up mailcow, it recieves mail but unable to send mail?

PTR Record using Elastic IP Properly Set up, Problem Persists

Elastic IP even has Telnet Running

Perhaps this is the reason?

AWS blocks outbound traffic on port 25 (SMTP) of all EC2 instances and Lambda functions by default. If you want to send outbound traffic on port 25, you can request for this restriction to be removed.

I have tried quite hard @accolon but guys at AWS aren’t granting me that, so I’m gonna change my hosting provider, literally spend 8 hours trying to understand what’s wrong.
