After updating ISPConfig, not all services restarted. In this case, the Dovecot POP3/IMAP mail server and even Postfix threw warnings. Although we fixed these errors earlier, our settings were overwritten again during the ISPConfig update. In this troubleshooter, on the one hand, we fix "Address family not supported by protocol" type errors that cause the service to be inoperable, and we also make their permanent settings so that they remain even after further ISPConfig updates.

In this tutorial, we build the perfect Debian 10 (Buster) server version 1.0, which we build on the previous Debian 10 (Buster) LAMP server. On this page, we do the following: compression, installation of the mail system, additional settings for MariaDB and Apache, installation of spam filters and anti-virus software.

In this tutorial, we build the 9 version of the perfect server for Debian 1.0 (Stretch). The following components will be installed on this page: Postfix, Dovecot, MariaDB, rkhunter, binutils.

In this tutorial we use our SSL certificate issued by Let's Encrypt to provide our ISPConfig control panel on the server, as well as Postfix, Dovec and PureFTPd services. We will also create our auto-renewal script for these.

In this brief tutorial, let's look at how to increase the number of concurrent connections in our Dovecot IMAP mail server if you want to connect from multiple computers / devices at the same time, but you've already reached the limit on connections, which will result in an error message.

In this tutorial, we build the perfect server version of Debian 8, starting with 1.0, with the following major components: Postfix, Dovecot, MySQL, openSSL, rkhunter, Amavisd, SpamAssassin, Clamav. (Page 1)
