Server receives email but no email is sent

Thanks a million for the points you mentioned, but, I am going to host more than one domain on this server.
If I change the host name to server.hitopex.com, can I use this same host for the other domains?
 
And one more question. When I create a zone only the host name and the ns are generated. Do I have to add the other records manually?
 
@BillyS why do you reply to me?

Yes. The hostname is the name of the server, it has nothing to do with the domains running on the server. However, it is used by all domains as the sending mailserver if you send mail, it connects by that name to other mailservers. But that is good, that is default.
You can host any domain on the server.

That is correct. At least.... it should contain all default records, so also mail and ftp and www and pop at least.
And if DA is setup correctly it should have a TXT record with an SPF line too.

If it has that, yes then it's correct. You should -not- need to add other records manually, if you don't see the ones I mentioned then things need fixing.
 
Thanks a million everybody. As Rihard kindly mentioned when a zone is created some fields are generated automatically but in my case only 3 records were generated after zone creation. So I should modify installing Directadmin.
I just did according to the guidelines in the following link:

Install guide | Directadmin Docs

DirectAdmin Knowledge Base
docs.directadmin.com
The installation took only 1 minute. I guess the prerequisites are not installed properly.
Now, I am going to install via the commands of this link:
bobcares.com

Install DirectAdmin Ubuntu

Installing DirectAdmin on Ubuntu, DirectAdmin allows the conduct of DNS, a list of accessible IP addresses, resource use data, and much more.
bobcares.com

Lets hope for the best,
Thanks again

Sorry, I did not know that the message is private when sent directly. I appreciate your help.
 
Hi everybody.
I think port 25 is not open and is open! I am confused! When I use the following command I get connected:
telnet mail.hitopex.com 25

But when I use either of the following commands, I cannot connect:
telnet alt1.gmail-smtp-in.l.google.com 25
telnet mx1.hotmail.com 25

Does it mean that port 25 is open on my server but not open on the ISP internet provider?
Awaiting your kind reply...
 
@fk21 why alt? it's just MX name, as I know google using smtp.google.com if you are about gmail-boxes.
If you about your own domain on google - they must provide you access credentials
 
I found that alt.. in the forum:

Cannot send email from Exim

Your inbound port 25 looks like it's open using this tool

Open Port Check Tool - Test Port Forwarding on Your Router

Port checker is a utility used to identify your external IP address and detect open ports on your connection. This tool is useful for finding out if your port forwarding is setup correctly or if your server applications are being blocked by a firewall.

Hi dear Billy,
Thank you for your help.

I changed the host name a couple of times using different structures: mail.hitopex.com, IP-Server.de, but nothing was affected.
May be I have done it the wrong way.
Do I have to change it for the Hetzner server?
I am a little confused because I use Hetzner DNS in Directadmin.
 
Please do NOT use mail.hitopex.com as hostname, it might cause issues. Keep using the name server.hitopex.com as hostname is better.
There is no need to keep changing hostname.

It seems everybody who told you to test port 25 has missed that information I posted in post #8.
It's not possible for you to send outgoing mail yet!

I will repeat what I wrote:
Richard G said:
Is it a real Hetzner server, or is this a new Cloud VPS? Because Cloud VPS systems can not send mail the first month.

And you answered you had a CloudVPS with Hetzner.
In other words.... you either have to wait or order a VPS with another party which does allow mail via port 25 instantly.
 
Hi Richard,
Thanks a million for your invaluable help.
Cheers, Faramarz
 
Hi dear all,
Thanks a million for your help.
I finally made it!
After eliminating the issues you all mentioned, Still I could not send an email.
The problem was data center not opening port 25!
I sent a request to open port 25 and the issue was eliminated.
Thanks a million for your help and care.
Warmest regards
Faramarz
