Hi,
I have installation of ‘cyberpanel’ + ‘Ubuntu server 20.4.06’ on my public home server, and I do the port forwarding for all and any ports that used by ‘cyberpanel’ , and DNS too.
Every thing is working well, but I have a small issue with the ‘E-Mails’.
When I try to send emails from webmail dashboard I didn’t see any errors or there is no any errors happening , and I get a success message , but the emails not arrived , and I have not receiving any messages on the mailbox that I try to send the message to.
On the other hand when I try to send a massage to any mail box I host on my server this messages received well.
We can consider that the server working only as a receiver and does not send any messages.
Although no error messages appear when trying to send as mentioned.
I try to send emails from my server to more than different email address , but the same issue.
Any ideas?!!
Thanks🙏🏻
