Problem in sending mail from vestacp
I have configured vestcp on centos 7.5. I have a website www.fabcultr.com
I'm not able to send any email, but I have no issue receiving email.
I have followed the solution provided in the below link
but still I have issue sending mails. Can any one please help me on this. Any thing wrong in the setup?
I get a bounce back mail. Have attached screenshot below
I am not sure if port 25 is blocked by digitalocean
can any one let me know what exactly is the issue. That would be great.
