I've spent the weekend experimenting with Docker and various Mastodon, Redis, and PostgreSQL set-ups, but for the life of me can't seem to get a working config. All of the Mastodon via Docker guides seem to be from a few years ago, before Plesk had a Docker extension, and talk about editing yml...

A lot of the sites that we host use one of two wildcard SSLs and each time we renew those, I've to go through approx 45 websites and update each of their uploaded SSLs individually despite the actual certificate being the same. As far as I'm aware, we're supposed to instead be able to use the...

One of our clients has had a pen test performed on their website, and the tester has asked us to remove the "Server: nginx" response header. We run the default Apache + nginx configuration on all of our servers and, as far as I understand it, this header is generated by nginx and cannot be...

One of our hosted websites has stopped sending emails. Investigating, I noticed there's a new "Track email delivery" under the domains Mail tab, and within this there's an action log which is currently showing a bunch of "Domains disk space limit reached" messages. E.g. The domain is indeed...

I'm part way through migrating websites from a CentOS 7.9 server running Plesk 18.0.59 Update #2 to Alma 9 running Plesk 18.0.60, and I've just noticed that if I click through to the mail settings of a transferred website, and then the "How to configure external DNS" link, the DKIM record that...

After my efforts to spin up a Rocky 9 server were swatted by Plesk not actually supporting Rocky 9, I've now spun up an Alma 9 server and worked my way back to being ready to install Plesk. This time I got the following error: So I enabled and tried again: And got the following: I then...

We have 3 CentOS 7.9 servers to migrate for separate clients, and as we're already running a Rocky 8 server for another client with Plesk installed to that just fine, I perhaps ignorantly just assumed Plesk would also run on Rocky 9 without problems. Having spent 2 days building the first...

Username: TITLE Issue DKIM signatures not applied when incoming mail disabled PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE Plesk Obsidian 18.0.52 Update #3 CentOS Linux 7.9.2009 PROBLEM DESCRIPTION When a domain's mail settings are set to "Disabled for incoming mail", emails...

I noticed Plesk now has 3 options for the per-domain mail service. Instead of just enabled and disabled, there's now a "Disabled for incoming mail" option which I presume means we can finally have the mail service running for generating emails through, without the server erroneously trying to...

We recently added DKIM to main domain, to combat some spam issues and get our sender reputation back up, but our server hostname is a subdomain of this domain and it looks like this is resulting in mailer daemon bounce emails being rejected because they're not sent with the appropriate DKIM...

We're having issues with our IP reputation on one of our servers causing some remote mail servers to now reject, or spam, emails sent from any domain that this server hosts and I think I've discovered the cause. Looking in the mail logs, it seems we're receiving a lot of mail sent to random...

I've just set up a new server for a client using a single domain Plesk license. Usually we use multi-domain licenses which of course include subscriptions and plans, so the settings I'm seeing in this install are a bit more restrictive but as far as I can tell everything is configured as per our...

I'm not entirely sure what happened with this one, but while transferring one of our websites, the migrator failed early on resulting in an empty subscription. I removed this and tried the migration again - this time successfully but ending with the following warning: Unable to restore the...

User name: QWeb Ric TITLE Mail not migrating properly if source server is Courier 5 PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE Plesk 18.0.21 Update #5 and Migrator 2.18.0-897. CentOS 7 on the destination server, CentOS 6 on the origin server. PROBLEM DESCRIPTION When...

We have an old server running CentOS 6.7 and a new server running CentOS 7.7. Both servers run Plesk Obsidian 18.0.21 Update #5 but the old server runs Courier mail, and the new is Dovecot. We have around 80 sites to import so we're working through them one at a time. Scheduling days with our...

One of our client servers suffered a filesystem corruption so we've set up a new server, installed Plesk, and then restored everything from Plesk backup to bring back the websites and various configurations. This mostly worked but we're having a few teething issues with this server now. One of...

We often get bombarded with malicious traffic from bad bots or infected sites hosted on particular networks, so when I find myself blocking the same IP ranges across multiple websites, or various IPs from the same network, I generally end up looking up the entire list of IP ranges belonging to...

TITLE: Spam filtering stops working when mail forwarding is enabled PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE: Plesk Onyx 17.8.11 Update #24, CentOS 6.10. Postfix + Courier mail servers PROBLEM DESCRIPTION: One of our clients often requests that we forward his emails to a colleague while...

We run 3 CentOS servers, each with Plesk. At 4am this morning one of these servers triggered the following email: And every hour has triggered the following: Presumably since the first error references Yum, Plesk must have brought in updates this morning that has for some reason messed up...
