Hello Folks. Good day. First of all, I'd like to Congratulate and Thanks the creator and contributor of this outstanding project. I discovered it very recently and I'm eager to put it to work. I'm facing few issues and I spent literraly hours on the forums to gather more information. I was able to get/solve few things, but there's some still to be worked. In this particular thread, I'd like to fix the issue I'm having with e-mail. I created a Domain and Mailbox using the ISPConfig Web Interface. I am able use RoundCube to login into that Mailbox and I'm also able to connect to that mailbox with a mail client (Evolution in my case). Even the auto-config works fine (as I have added the SRV records to help with that). The issue is that, althought I got no error when sending a message, the message is never delivered neither returned... Same thing when I try to send a email from another domain to this inbox... I got no error on the client but the message are not received on my domain. If I send an email to myself, nothing is received (no message, no error (but I can see the message on the "sent" folder)) I'm providing my setup information below. I really hope somebody can shed a light on this issue. Thank you.

Log shows errors: Code: Recipient address rejected: User unknown in virtual mailbox table That is why that mail can not be delivered. The sender should get some feedback, though. Another error: Code: connect to 127.0.0.1[127.0.0.1]:10026: Connection refused Looks like e-mail setup on that server does not work. Verify configuration files, compare what is in the Perfect Server Guide. Or how did you install this host?
Hello @Taleman. Thank for the reply. Well, I checked several files and didn't find anything obviously different. I then decided to delete everything and start over again, installed from scratch, from OS installed and following meticulously the Perfect Server guide. Websites are created ok, Let's encrypt certificates generated and installed, ok. But email continues behaving the same way, not error from roundcube when I send a message from it's interface, but message is not delivered to the destination and it's neither returned.. The same way, if I send the message from a external provider to the server email, not error is returned but no message is delivered.... Anyway.... What config or log files do you need recommend me to post here to help fix this problem. Again, Thanks a lot.
My signature has link to e-mail tutorial, compare that to what you have done so far. Tutorial has some troubleshooting instructions.
Seems as if you are using a setup with amavisd and amavisd has not been started. This happens e.g. when there are problems with our hostname setup. Try to start amavis and if it does not start, check mail.log to see why.
Hello. Thanks for the feedback @Taleman and @till. I was able to find and solve the issue. It was, indeed, related to amavis service. This was what I was getting on service status: Code: ● amavis.service - LSB: Starts amavisd-new mailfilter Loaded: loaded (/etc/init.d/amavis; generated) Active: active (exited) since Mon 2021-12-06 10:33:20 -03; 1h 7min ago Docs: man:systemd-sysv-generator(8) Process: 1854 ExecStart=/etc/init.d/amavis start (code=exited, status=0/SUCCESS) Dec 06 10:33:20 server.fqdn amavis[2513]: Net::Server: 2021/12/06-10:33:20 Amavis (type Net::Server::PreForkSimple) starting! pid(2513) Dec 06 10:33:20 server.fqdn amavis[2513]: Net::Server: Binding to UNIX socket file "/var/lib/amavis/amavisd.sock" Dec 06 10:33:20 server.fqdn amavis[2513]: Net::Server: Binding to TCP port 10024 on host 127.0.0.1 with IPv4 Dec 06 10:33:20 server.fqdn amavis[2513]: Net::Server: Binding to TCP port 10024 on host ::1 with IPv6 Dec 06 10:33:20 server.fqdn amavis[2513]: (!)Net::Server: 2021/12/06-10:33:20 Can't connect to TCP port 10024 on ::1 [Cannot assign requested addr> Dec 06 10:33:20 server.fqdn amavis[2513]: sd_notify (no socket): STOPPING=1\nSTATUS=Server rundown, notifying child processes.

After enabling it, the amavis service was started working and emails are now being received and delivered. Thanks a lot for the help. Best Regards.
Alternatively, Adding the following line on the /etc/amavis/conf.d/50-user also makes amavis not require IPv6 to work. Code: $inet_socket_bind = '127.0.0.1';
