Can receive but not send emails

jdesousa

Hi there,
I am very new to email servers and the sort.
I recently set up a mailcow server but I am having problems sending emails.
What would be some things to look at in this situation.

I have tried the solutions for this problem listed here: https://mailcow.github.io/mailcow-dockerized-docs/debug-common_problems/

Thanks!
Jacob

Any details? What problems do you have?

You may send a test mail to https://www.mail-tester.com/ to chck for general problems.

This is the message I get after sending an email to my own address.

I have UFW disabled on the ubuntu server. I also have all ports opened on my host.

Can you telnet to that IP/port from your machine? telnet 104.47.33.33 25
