Hi everyone, just a warning, so that you can get around this silly feature / nightmare with your customers losing trust in you as a serious hoster. Tonight, we did a planned Database cluster maintenance and upgrade. Everything went well and smoothly, but as planned, the application servers were...

Dear Plesk community, in order to make our Mailserver more secure and feature rich, we're using: - Plesk Premium Email (Kolab) - Plesk Email Security (Spamassassin + ClamAV) - Plesk Premium Antivirus (Dr. Web) Now since ClamAV doesn't even recognize simple Macro viruses in Word files, I had to...

Same Problem on Debian 9.12 (no dist-upgrade) with Plesk 18.0.28-2.

Hi Peter, thanks for your suggestions, everything is setup correctly. Connections via ipv4 / ip6 are successful (accessible from remote / different networks, the .well-known folder and its contents are callable). The reason is the mentioned redirection. Disabling it solves the problem. This...

Since the update, I get the error message below, when the SSL extension tries to auto-renew a certificate: Invalid response from https://acme-v02.api.letsencrypt.org/acme/authz-v3/12345. Details: Type: urn:ietf:params:acme:error:connection Status: 400 Detail: Fetching...

Hi @AYamshanov - thanks for the great extension! One question: I tried to install Percona's genius Monitoring PMM2 (Download Percona Monitoring and Management 2) in parallel, but I didn't manage to get any numbers from the server that has Plesk installed. All other servers went fine with it out...

- did you compile Apache by yourself or is it the out-of-the-box version? - did you set any additional Apache (http / https) settings in Plesk?

Hey everyone! 1) I'm having some trouble with my Kolab configuration. As I've tested a few things, I'm not sure anymore if a config file was set by me or the Kolab setup itself. In /etc/dovecot/conf.d, is the file "99-special-use-default.conf" meant to be there or did I include that by myself...

Did you try any of the proposals/ideas?

Is your server's loopback interface working (that it can successfully resolve 127.0.0.1)? Other suspect settings: The content_filter ("amavis") must be setup as transport in the master.cf with the same name. In this case, it's called "smtp-amavis" in the master.cf, not "amavis". That may be...

Hi @IgorG, Thank you for forwarding my message! Unfortunately, the link you provided doesn't work (at least on my machine). Is there any way or anyone I can contact to ask about bypassing guam and what are the implications on that? Apart from that, it'd be nice to have a notice or an error...

TITLE: Dovecot SNI not working with Plesk Premium Email Extension (Kolab/Guam) PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE: Version 18.0.21 Update #5, Debian 9.11 PROBLEM DESCRIPTION: When setting up SNI in the new Plesk Obsidian, certificate also configured for each domain's email...

I've been investing some serious hours to get Postfix/Dovecot working with SNI certifiactes and the Plesk Premium Email Extension (Kolab) now. However, echo | openssl s_client -connect localhost:993 -servername xyz.com will keep returning the global server's mail certificate, not dovecot's...

Just for the completeness of the post - IMHO one of the best nameserver providers is DNS Made Easy (DNS Made Easy | Fastest and Most Reliable Enterprise DNS Provider). It is not only speed that matters, but it helps ;) and there are tons of other features (including hidden primary / secondary...

You "made it work" for the OP, so everything is good. I just wanted to chime in and tell about the risks - reflection attacks and bad recursion settings are only two examples. People tend to leave their aging servers (old OS and Plesk versions) open in the internet, which are being used as...
