Hello guys, I'm a beginner with the ISPConfig and Postfix. So, my apologies for any dumb question here. At my boss's request, I installed ISPConfig on a CentOS 8 machine on AWS some time ago. I did some tests and can't send emails at all. Checking this forum's posts, I've found some really nice tips about how to make things work. But due to a carelessness of mine, I forgot how to access the IPSConfig control panel. I've tried to access using: https:// hotsname.com :8080 http:// hotsname.com :8080 https:// ipaddress :8080 http:// ipaddress :8080 Also tried with "/login" at the end and with the 80 and 81 ports, no results at all. I'd be very grateful for any tip on how to access the panel again, how to change the access URL or even how to clean up the installation so I can reinstall it without any bugs. Thank you very much.
Any of the https:// URL's will work as ISPConfig listens on all IP's and domains o port 8080, with IP you will get an SSL error though as SSL certs are for domains and not an IP. If its not on port 8080, then you either changed the port manually or the web server is not started (or your IP or hostname does not point to an ISPConfig server). You can e.g. check with: netstat -ntap | grep 8080 if there is a process listening on that port. In case you want to reinstall, use Debian 11 (12 not supported yet) or Ubuntu 22.04 and not CentOS. Debian and Ubuntu are the recommended distributions, installations are much easier and more stable than on centOS. Plus you can install it automatically using the auto installer: https://www.howtoforge.com/ispconfig-autoinstall-debian-ubuntu/
Thank you for the answer, but since that my boss's told me to, I really need to use CentOS. =( I tried netstat -ntap | grep 8080 but the command wasn't found. Then I tried sudo yum install net-tools and got the "Killed" result. Is there any way to change the access URL?
Did you install the server with apache or nginx? maybe its bets you run the test script and post the output, so we can help you better: https://forum.howtoforge.com/threads/please-read-before-posting.58408/
We have many CentOS servers on the company I work, all with WHM/cPanel and EXIM running, with which I have some more experience. So my boss's to get rid of many cPanel's bugs choose ISPConfig, and of EXIM's bugs choose Postfix, and asked me to learn how to configure a server with this tools from scratch. I've installed the server with apache as my web service. Here's the output of my test script: Code: ##### SERVER ##### IP-address (as per hostname): [localhost] [WARN] could not determine server's ip address by ifconfig [INFO] OS version is CentOS Stream release 8 [INFO] uptime: 17:03:58 up 5:21, 1 user, load average: 0.00, 0.00, 0.00 [INFO] memory: total used free shared buff/cache available Mem: 808Mi 329Mi 249Mi 25Mi 229Mi 338Mi Swap: 0B 0B 0B [INFO] systemd failed services status: UNIT LOAD ACTIVE SUB DESCRIPTION ● dnf-makecache.service loaded failed failed dnf makecache LOAD = Reflects whether the unit definition was properly loaded.

Did you run the test script as root user? And if he would have chosen Debian 11 or Ubuntu 22.04 as basis, he would have got rid of the CentOS issues as well The main problem of CentOS and other RHEL derivates is the lack of a central repository that provides all packages in a uniform way. Yes, there is Epel and Remi but it does not match stability-wise what you get with Debian and Ubuntu as a platform.
Yes, I run the command logged as the root user. I really didn't know that. Even not knowing if he will accept, surely I'll suggest that we change the CentOS too.
Man, sorry, I made a mistake, the server distro is already Ubuntu. I was reading a tutorial on How to Forge named "The Perfect Server CentOS 8 with Apache, PHP, Postfix, Dovecot, Pure-FTPD, BIND and ISPConfig 3.2" and got confused. Now I'm able to access using my ip address with https. I'll search in the topics something to help me with the mail sending problem. Just a question, is there a way to access using the subdomain that I define as host? Just if you need, there's my test script results: Code: ##### SERVER ##### IP-address (as per hostname): ***.***.***.*** [WARN] could not determine server's ip address by ifconfig [INFO] OS version is Ubuntu 20.04.6 LTS [INFO] uptime: 19:07:09 up 66 days, 6:31, 1 user, load average: 0.02, 0.07, 0.05 [INFO] memory: total used free shared buff/cache available Mem: 976Mi 450Mi 82Mi 11Mi 443Mi 358Mi Swap: 0B 0B 0B [INFO] systemd failed services status: UNIT LOAD ACTIVE SUB DESCRIPTION 0 loaded units listed.

That's the default already. Maybe you missed pointing this subdomain to the server before installing ISPConfig? The next steps are: 1) Check that you pointed this subdomain to the right server in DNS. 2) Check that you configured it correctly in the os of the server, you can do that with the command: hostname -f it must show the correct fully qualified domain name of the server, e.g.: server1.example.com 2) If 1 + 2 are correct, run: ispconfig_update.sh --force to update ISPConfig and chose to reconfigure services during update. When the updater asks to create a new SSL cert, choose yes. Regarding your mail problem, seems as if postfix was not configured before you installed ISPConfig, most likely, you used one of the manual install guides and missed that step to configure master.cf and not the auto-installer, which does it automatically.

At least lines #submission and #smtps are commented out. Compare what you have written to that file to the ISPConfig installation instructions you used.
I reviewed and compared the master.cf of Postfix, making the changes to be exactly as the perfect server tutorial, and now, I'm no longer receiving timeout error in Roundcube, the message is that the email was sent, but it did not reach the mailbox I sent. Also, when I test the sending using an online SMTP test (https://dnschecker.org/smtp-test-tool.php), I can only send emails with the 25 port, but can't send with the 587 port, is there anything I can do to change it?
What is in mail log when message is being sent? If your server log says message was sent, it is in the receiving e-mail server. If the message does not appear in the receiving mailbox, it is the receiving sender that has discarded the message, put it in SPAM folder or maybe the e-mail client moves message to SPAM? It would help if you showed exactly what the test tool diagnosed. I assume you did read my e-mail tutorial completely?
