Hello, after a long time back and forth I managed to install Ispconfig manually because the AutoInstaller unfortunately didn't work with the Raspberry. With the instructions: The Perfect Server - Debian 10 (Buster) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.2 The only thing I changed there was the PHP version instead of 7.3 I took 7.4. Everything works except for sending and receiving emails. This is in the email queue: Code: -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- 0F8ED3A17F3 558 Fri Sep 2 16:31:26 [email protected] (host 127.0.0.1[127.0.0.1] said: 451 4.5.0 id=136105-01 - Temporary MTA failure on relaying, From MTA() during fwd-connect (All attempts (1) failed connecting to smtp:127.0.0.1:*): id=136105-01 (in reply to end of DATA command)) [email protected] I got a domain from Strato that I entered in my FritzBox router via Dynamic DNS. (Works without problems) The server runs on my Raspberry Pi 4 with 8GB with Debian 11 (Raspi OS) In the FritzBox I have released all ports that are required.

Which command line options did you use for the auto-installer? There are known issues when you force the auto installer to use amavis, but amavis should not be used anymore anyway. And as long as you use Rspamd, which is the default, there are no issues. If you have used amavis option manually in auto-installer, then you can try this: Go to system > server config > mail in ISPConfig, there choose Rspamd as spam filter, press save, switch back to amavis and press save.
Unfortunately, the auto installer did not work on the Raspberry. But that was also as information in the arm is not supported. That's why I used the old installation instructions. howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/ I just changed the php version to 7.4. But it can also be that it doesn't work because I use Strato dynamic dns which runs on my FritzBox and unfortunately I can't make any DNS entries - everything is just set to inactive. No subdomains work in ISPConfig either.
So we should first check if it's an issue on the server or a DNS or firewall problem. Please try to do what I suggested in regard to switching between amavis and rspamd setting as this forces the config to be rewritten. Then run the test script as root user and post the result: https://forum.howtoforge.com/threads/please-read-before-posting.58408/
I had tested it with amavis and rspamd but unfortunately without success! I also think it's a DNS problem. But since everything is blocked at Strato because of the dynamic DNS, I can't do anything about it. Just can't edit DNS or A Record. Even in ISPConfig if I make DNS entries there, they will probably not be accepted.

Text in German don't know if Google translates it so perfectly: Ich hatte es getestet mit amavis und rspamd aber leider ohne erfolg! Ich denke auch das es ein DNS Problem ist. Aber da bei Strato alles gesperrt ist wegen der Dynamic DNS kann ich da wohl nichts machen. Kann einfach kein DNS oder A Record bearbeiten. Auch in ISPConfig wenn ich dort DNS Einträge vornehme werden die wohl nicht übernommen.
Just to say I have ISPConfig running on a couple of RPi4's with email working just fine. One is a fresh 64 bit Bullseye install based on using the Debian 10 tutorial as you did. The other is a 64 bit Buster to Bullseye upgrade using the ISPConfig upgrade tutorial. Almost everything works. Goaccess doesn't. They are on static IPs which may indeed support your Dynamic DNS suspicions.
I've changed that now /etc/postfix/main.cf Code: mydestination = whazzza.de, localhost, localhost.localdomain to Code: mydestination = localhost, localhost.localdomain Now it works that I can write an email to myself. But I can't send email anywhere else like Gmail, Gmx...... Now the problem seems to be that the DKIM key is not taken. Although I inserted it as you can see in the picture.
Domains sued for email addresses may not be listed in mydestination indeed, that#s why the server hostname always has to be a subdomain (see perfect server install guides). Remove the "" within the key string (the part after p=).
I know, but unfortunately subdomains don't work, that's why I tried it without a subdomain. I removed both "" characters present in the key. So far, sending emails to GMX or Gmail still doesn't work. But maybe it takes a while until the entry is accepted.
Adjusted a couple of things. /etc/postfix/main.cf Code: inet_protocols = all to Code: inet_protocols = ipv4 And then I entered that into SPF Code: v=spf1 a mx ip4:192.168.xxx.xx ~all The emails are now arriving at Gmail. Only with GMX I still get the following errors. Code: (host mx01.emig.gmx.net[212.227.17.5] refused to talk to me: 554-gmx.net (mxgmx104) Nemesis ESMTP Service not available 554-No SMTP service 554-IP address is block listed.
