Firstly, let me thank you for your support Secondly, about send an email to the same address I already did that and it working very well as screenshot, and what about external mail system and how can set a proper username and password for relaying how can I do that can you give me the steps PLZ. Thanks a lot

Do you know what the username and password are? Why are you setting up relaying via external e-mail server?
How could anyone on this forum know your passwords? Ask the party that offers you the relaying e-mail server, what is the username and password needed for that service. Or think if you actually need to relay outgoing e-mails at all. My signature has link to e-mail setup with ISPConfig tutorial, maybe it offers some help?
I buy only domain form GoDaddy and do the DNS records and setup up server ISPCONFIG and linked between them by do port forwarding to my private IP to Public IP that's all I did and I don't know about relaying email server and how can I get that or from where can advise me how can I get that Note: that is the first time I do email server so I don't know all steps or what should I do thanks for your support,
Dears, I need your help I don't know what is the authentication for relaying and how can I get that from where just I need send the email from my domain mail-travel to another domains like google, outlook , yahoo, any domains In this moment I can't, can any one experts explain to me what should I do by steps. Thanks for always support.
Google is your friend. First learn what is the meaning of such term(s) and its related things e.g. email, email server, email server requirements, email ports, email relay, email username/address, email password, email authentication etc. Without proper knowledge, setting up an email server is definitely not as easy as 123 as many newbies would like to think. A lot must be learned and understood (like some of the terms I mentioned) before you can succeed in building one. Running and maintaining it will be another issues altogether. Only serious server admins will do that. That said, if you need to send email from your domain, the easiest way is to use any web hosting services which normally have it ready. The other one is to use email paid service like google where you can also use your own domain to send emails, like what web hosting services have. Otherwise, if you really want to send it on your own, there will be two options, setup an email server (not advisable for total newbies) or use a relay. The latter is easier, since you only need a working free public email that offers such a relay service. How it works? Refer to that public email documentations and google more on it. And please do not PM me for help. If I am helping in here, I do not intend to help only a single user but the whole public, so please make use of the forum and do not abuse it. I might ignore those who do the latter.
If you run your server in a datacenter that does not restrict access to and from port 25, then you do not have to relay emails. I guess you probably either run your system at home (and most internet access providers for home or office use restrict mail sending) or you use a datacenter or cloud provider that does not allow direct mail sending, in such a case you need a mail relay. A mail relay is a server in the internet that will send the emails for your server as your server can not send the emails itself due to external restrictions of the internet access provider (like a firewall with port 25 closed). If you have to use a mail relay server, then you can set its details like server hostname, username and password in ISPConfig under system > server config > mail.
Really thanks for this information let me ask you can I add port 26 to send with 25, if it can help and how can I do that Note: when I do the configuration email on outlook it is valid as photo it is refer to anything or not and I did telnet from inside network on server and outside network. are that refer to anything?
Firstly, thanks for your support Secondly, I am not use anything to support or help when I send to you private I send because I guess you in your work and I don't know you can see all posts or not so I did that.
There is quiet a good book to get into it by Alistair McDonald , Magnus Back and David Rusenko it's called "Linux Email" published by Packt. May start there or any other free resource, and read into the topic.
Port 25 is needed incoming and outgoing if you want to operate your own mail system without a relay server. You can not chose a different port as no other mail system on the internet would know it, any system will try to connect to your system on port 25 and your system (or the relay server) must connect to other mail servers on port 25.
let me ask you if I do telnet outside on server by port 25 and it is successful that 's refer port 25 working well maybe telnet successful but it's blocked from ISP so I can't send emails to any different domains. but when I add the config to outlook it give me the port successful as photos, and I think this error from server can you check with me again this server working very well or not.

telnetting to your mail server on port 25 is one thing.. your mail server connecting to other mail servers on port 25 is another thing entirely. you mail server needs to be able to receive connections on it's own port 25, and make connections to other servers on their port 25. this does not mean your mail server makes the outbound connection from port 25, (it'll use a random port number) just that the destination port is 25. this is what the isp may be blocking, outbound connections from any port on your ip, to another servers port 25. you've also configured your mail client to connect to port 25 on your mailserver, with no encryption.. you should not do this. for mail clients outbound connections, set it to use port 465 or 587 and SSL/TLS or STARTTLS. only smtp between MX servers should use port 25.
firstly, there any error in server did you see the report ? how can I check that ISP block the port ? Thanks a lot
Then you have to use a relay host for your server or do not host your server in a data center and not at home. The lxd service is not used by ISPConfig on your system and its also not related to email, so it does not matter if it failed. not any error you see matters for a specific issue. First, take care telnet is installed on your server: Code: sudo apt install telnet Then run this command to test outgoing email connections: Code: telnet gmail-smtp-in.l.google.com 25 If the connection was established successfully, then you can close it using the command quit. The result should look like this if its successful:
