I can not send email

[bruno]

Hello guys. I get email but can not send. To send, but the person does not receive. Use CentOS 7. Can someone help me?

Did they check their spam folder? Is port 25 blocked in your server? What do you mail logs reveal?

You should unblack list the ip and request it's removed. Ensure that your server is clean too and no virus there.
