Sorry , it's my first topic related at this theme. I'm freelancer , work with wordpress , php , javascript , and now I decided to start my own website (a comercial wordpress blog) and buy a Unmanaged VPS Host (my bad). I read a lot of things about how to manage a VPS host (little, as shown). I have a virtuozzo VPS on CentOS , and I instaled Kloxo to manage easier the host. I had a lot of problema, but this problem struggle me for some days and I decided to find help here.
I contact the host for support , and this is what I received (can be help another person who will meet the same problem):
your server is listening on both ports 25 and 26:
--------------------------------------------
[root@server /]# netstat -ntap|grep :25
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 14085/xinetd
[root@server /]# netstat -ntap|grep :26
tcp 0 0 0.0.0.0:26 0.0.0.0:* LISTEN 14085/xinetd
[root@server /]#
--------------------------------------------
To utilize this functionality, you need to setup your mail client on your computer to use the mail address from the server, like test@yourdomain.com or any of the other addresses belonging to yourdomain.com domain, not example@gmail.com, and to send mails over the server through port 26.
No ISP should be blocking port 25 ever, as it's a port that mandatorily needs to be open as per RFC-standards, and disabling it is a really bad, improper and user-unfriendly (and not very successful) way of attempting to block spam.
I thank you very much for your help, is a great forum and I will definitely come here to ask something or to help others.
Now I can receive email from my server and I'm very glad.
WHM is "Web Hosting control panel system"
That's almost certainly incompatible with SME server, and you will have numerous problems if you attempt to use WHM and SME server together.
So can I manage the host without a control system , by console is hard.
P.S. Sorry my English , is my 3'rd language .
