Hello, Debian 4.9.168-1+deb9u4 (2019-07-19) x86_64 ISPConfig Version: 3.1.14p2 single Nginx I am migrating the mail from my old ISPConfig server to the new one. I encounter two major difficulties of setting. 1. The incoming imap server does not use encryption. How to specify STARTTTLS encryption in ISPConfig? 2. To handle spam, I use ManageSieve on the principle that everything is denied except email addresses and authorized message titles. On the new server, I can not add new filters from Roundcube. I can write it by hand on the .sieve file of the e-mail address on server. How to set [and where?] Email to accept very large numbers of filters?
1) Ensure to install your server according to the official ISPConfig installation instructions (perfect server guides) to get a fully working system. 2) Managesieve is not used on ISPConfig systems. Custom sieve rules can be added in ISPConfig either by using the filter editor in the mailbox settings or by inserting custom rules in the custom rule box of the mailbox.
1. I followed the explanations of the tutorial "The Perfect Server - Debian 9" (Nginx, BIND, Dovecot, ISPConfig 3.1) "and I added the commands that were missing In the manual, I saw that it was also necessary to add the IP server in "/etc/postfix/main.cf". All this is not enough to set up encryption on IMAP and Thunderbird expresses its dissatisfaction. So there is something missing that I have not seen. What is the relevant manual page? 2. The Sieve filtering done by ISPConfig is very largely insufficient! It can not be good when you receive a lot of messages every day. By doing some tests, I discover that ManageSieve refuses to record new filters as soon as we exceed 55 rules in a filter. It is therefore a simple setting somewhere. Yes, but where and how to find it?
The manual is about multiserver systems and not single server setups as you have it according to your first post. there is no IP to be added in main.cf on your server. So which rules cannot be added to the custom rule field that I mentioned? Actually, you can add any rules you want there that are supported by sieve. And regarding your IMAP question: Maybe you did not accept the self-signed SSL certificate in Thunderbird. If you want to have a cert from let's encrypt instead, then install one from let's encrypt: https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/ Or the imap subdomain you are using does not point to the right server.
1. OK. What to do. 2.Whenever I have a new client, for example Claudine Dupont with the email address [email protected], I insert the following rule in the filter in alphabetical order, for example, between Claude Durant and Claudine Pupon: If possible with ISPConfig, how? It starts to have a lot of rules, so it needs to be fast and easy to write... This method of denying everything except the recognized clients eliminates me about 120 000 spam a year.
Sure, that is and was already possible in any ISPconfig 3 version from the beginning. Just paste the rules into the custom sieve rules field. That's why the custom rules field exists, its way faster to add multiple rules there than using managesieve.
It's a good and pleasant thing. How to make these filters copied in ISPConfig also appear in Roundcube. I followed the tutorial "ISPConfig 3 mailuser interface for roundcube", but they do not appear. In other hand, they appear well in the Filter menu of Managesieve ... with always the same problem: the limitation to 55 rules by filters if I want to register a filter which already contained more than 55 rules.
