Sentora Support Forums

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?

Im having this problem too able to receive mail and sending successful (but people NO receive any email) Junk mail checked is not inside too

new clean server setup
but still dont know where went wrong





checked with Rdns (but im not sure where to set the rdns)

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