ISPCONFIG 3 web site not display

invalid@example.com (hiperbiper) — Tue, 10 Mar 2026 11:55:21 +0000

I installed it from the link and it worked.

This morning, the ISPCONFIG page is missing, and I can't change the settings. I ran ispconfig_update.sh --force but didn't make any modifications to the database. I just generated a new certificate—it didn't help. What's causing this? My apache sites-enabled

Debian 11->12 upgrade. Email not sending

invalid@example.com (chrisale) — Mon, 09 Mar 2026 20:51:59 +0000

Hi again all,
The last problem appears to have been related in part to upgrading from Debian 11->12, even though I did so on a brand new server. So I'm going out on a limb and hoping this is similar this time and give a clue as to the problem.
Short Version: I can't send email.
Either from the command line or from webmail for a created email mailbox.
The squirrelmail interface simply says this:
"SMTP Error (): Authentication failed."
The mail.log file output is a little different though,...

invalid@example.com (Yarnell) — Mon, 09 Mar 2026 17:32:51 +0000

Hey all,

I noticed that there was a webmail present on port 8081
What is the difference between the 2 locations:

Code:

https://localhost/webmail

Thanks

Change to rspam

invalid@example.com (Shyciii) — Mon, 09 Mar 2026 08:19:39 +0000

Hello,
How do I switch from an existing amavis-based ispconfig3 server to rspam? I can't find any instructions on how to do this.

How ISPConfig manage SPF/DMARC for incoming mails ?

invalid@example.com (francoisPE) — Sat, 07 Mar 2026 06:24:46 +0000

Hello,
I have ISPConfig 3.2.7p1 configured with email domains and email boxes.
I wonder how my server is dealing incoming mails regarding SPF directives and DMARC directives ?
Does it consider SPF record when receiving a mail and reject if violated ?
How does it consider DMARC directives ? Does it send a mail like no-reply-dmarc@mydomain.tld ?

Deleted Server Entry In Ispconfig

invalid@example.com (MarvinFreeman) — Tue, 03 Mar 2026 14:41:03 +0000

I deleted a server from ispconfig by mistake. How can I restore the entry?
I simply hit the red garbage pail for the wrong server. Yes, I do feel like a moron.

Error with a2enmod stops autoinstaller

invalid@example.com (MarvinFreeman) — Tue, 03 Mar 2026 09:13:25 +0000

I am installing ispconfig (having uninstalled an earlier installation) using the autoinstaller. It breaks with this error:

I've tried removing and re-installing apache2.
Running the command directly gives this error:

new install, the mail server cert is giving the hostname instead of the alias mail.

Greetings all, I seem to have forgotten how I did something many years ago.
As requested in the "Please read before posting" thread, my system stats are:
Ubuntu 24.04.4 LTS
PHP CLI version 8.3.30
NGINX
and the output of cat htf_report.txt is at the bottom of this post.

So, I have been using ispconfig since version 2something. My old server was getting rather long in the tooth, I think it was created with the release of ispconfig3, and has been through all the upgrade cycles to current...

invalid@example.com (BudSpencer) — Sun, 01 Mar 2026 15:58:13 +0000

Any help/tutorial/advise and so on, is appreciated.

security and access to /phpmyadmin on 3.3.1

invalid@example.com (Krikey) — Sun, 01 Mar 2026 15:51:07 +0000

I've noticed that users can access the login page for phpmyadmin from any domain that's hosted on the server. ie example.com/phpmyadmin
I'm not sure if this has always been the case as I've always used the link and icon presented within ISPConfig. Whilst both are just public links, what are your thoughts on security of having this for each and every domain that's hosted as it presents as multiple attack surfaces?
How would one go about limiting access to only the URL thats listed in the...

clearing up mixed debian versions, installing mysql?

invalid@example.com (theTJ) — Thu, 26 Feb 2026 14:28:57 +0000

hi,

I'm in the process of setting up a new cluster of servers controlled by ISPConfig.
Because I started this process before 3.3.1 was released I now have some debian bookworm instances (mainly the ISPConfig main host, two web and one database server) and some (mainly kind of "staging" server one web and one database) already on debian trixie.

All Servers are alredy on 3.3.1 so my question is what should be the simplest way to do an dist-upgrade with minimal disruption?

Per-vhost error logs empty after nightly rotation since last ISPConfig update

invalid@example.com (ColonelPhoenix) — Tue, 24 Feb 2026 09:42:31 +0000

Since updating ISPConfig (~1 week ago), per-vhost Apache error logs (/var/log/ispconfig/httpd//error.log) stopped receiving entries after the nightly log rotation. The same behavior is observed on all servers where the update was applied. On some servers we only have logs during 00:00 and 00:05, on some other we only have logs between 00:00 and 02:00 AM.

Observed behavior:
- Rotated error log files now only contain entries from midnight to ~2 AM (2 hours), whereas before the update...

Hi,
I ran the Auto-Installer on a clean Debian 13 server and if I enable the E-Mail backup then I get this error message below:

small issues after upgrading to debian 13 (app-vhost+php)

invalid@example.com (noonecanhide) — Thu, 19 Feb 2026 19:05:48 +0000

The update itself went smoothly; manual intervention was only required when switching from PHP 8.2 to 8.4. Everything also worked fine with Dovecot.
But, there are some small issues i want to check:
I’m having a problem accessing the app vhost — both Webmail and phpMyAdmin are throwing a 502 error.

The cause appears to be a conflicting configuration between Nginx and PHP, or possibly something missing on my system. The migration was done at the time from an existing Debian 11 + ISPConfig +...

PHP module installation oddities following upgrade from Ubuntu 22 to 24

invalid@example.com (Instanerious) — Thu, 19 Feb 2026 18:29:53 +0000

After following the guide to Update the ISPConfig Perfect Server from Ubuntu 22.04 to Ubuntu 24.04, I tried to change my Nextcloud site to use PHP 8.3 instead of the previous 8.2 (or 8.1). The obvious next step was to review PHP installation, configuration, and modules.

I found some modules which were installed for 8.2 for not for 8.3, so I tried to install them. The installation failed with error "Unable to correct problems, you have held broken packages.", but it appears that ubuntu22...

Server Config (IPv6 Prefix) Bug or User Error?

invalid@example.com (Outbreaker) — Thu, 19 Feb 2026 07:11:50 +0000

Hi,
The option says I should add an "IPv6 Prefix" but if I add "220a:2dc0:c1:5295::/64" then it say wrong IPv6 Prefix. But adding "220a:2dc0:c1:5295::" works, but I have the feeling that adding without "/64" this is incorrect or?

relay for specific domain

invalid@example.com (tr909192) — Wed, 18 Feb 2026 07:58:17 +0000

in a master/slave setup i need to send all email outogoing from a certain domain to a specified relay with user and pass, without touching general sending.
in db it should be;
UPDATE mail_domain SET relay_host = '[smtp.altroserver.com]:587', relay_user = 'utente@altroserver.com', relay_pass = 'PASSWORD' WHERE domain = 'dominiocliente.it' AND server_id = 38;

is there a way to do that from the ispconfig?
