I've been having problems using PHPMailer with attachments and DKIM, receiving instances are saying the DKIM signature is invalid, the body has been modified (without attachments the dkim signature is valid). So I wanted to check out the differences in the canonicalisation algorithms, which is...

Thanks to @sebgonzes for linking up. Indeed I have been wondering, when a staff member can reply to this issue? @IgorG - can you write something about this issue? Thanks, Tim

Possibly my post Postfix SNI TLS-Certs not auto-updated and this one are related, I'm not sure: By what mechanism are these SSL renewal processes started? Thanks, Tim

This morning I could not send mail from some accounts, Thunderbird said the certificate has expired. Problem: When selecting "SSL/TLS certificate for mail" in the mail settings of an individual domain, the certificate for Postfix for that domain is stored by Plesk in...

Many thanks to @learning_curve - yes, that linked article describes exactly what I'm seeing. And good to read that it's a registered bug in SSL It!, so we can hope for a fix in the not too distant future. Will just delete the erroneous mails until then. Other than that, the SSL It! extension...

I'm seeing mails like this - every day: Renewal of the following Let`s Encrypt certificates has failed: * 'Lets Encrypt timreeves.de' [days to expire: 89] [-] *.timreeves.de [-] timreeves.de Could not retrieve dns service status: DNS service is not enabled and Renewal of the...

Well, "www." to a subdomain would be something like "www.mail.example.com". Normally there will be no DNS entry for that, so verification would fail. Maybe it's a feature, not a bug?

Well now I'm bamboozled: I tried adding a new account in Thunderbird anyway, and it looked like TB had got the data. So I checked the TB console log, and yes: 2019-11-07 18:21:57 mail.setup INFO call 1 took 130ms and succeeded at <https://(redacted).space/autodiscover/autodiscover.xml>...

This new feature is attractive, so I wanted to activate it. I did, but Thunderbird was obviously not getting the data. I debugged the feature, trying to call the URL which Thunderbird would use: 400 Bad Request. I tried this on 2 different servers, one with an external FW in front of it, the...

I run Plesk on about 7 servers, all Debian 8 or 9, all without Bind installed (the Domains are all managed at domain specialist companies). All Updating is going fine everywhere, except at one server I am now seeing the warning popup (bottom right) when logged in to Plesk: Failed to update the...

I'm just configuring a new vServer with Debian 9.5 / dovecot 2.3.0.1. When I restart the service I'm seeing: dovecot[19544]: master: Warning: service auth { client_limit=1000 } is lower than required under max. load (1224) dovecot[19544]: master: Warning: service anvil { client_limit=1000 } is...

TITLE: Plesk Dovecot Config contains obsoleted statements PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE: Plesk 17.8, Ubuntu 14.04 PROBLEM DESCRIPTION: It seems that dovecot has been updated to 2.3.0.1 This version has some changes in ssl configuration which have not been updated yet in Plesk...

I assume it should work for CentOS too, as we are talking about the database entries - I can't imagine any reason why they would be different. But I don't know for certain as I don't have any server with CentOS. I recommend to just try it - after all, you can easily revert by making a change in...

I've still been having problems, with the zabbix repo not being able to be read sometimes. When I click on the links in the error report, there is no problem, they work fine in the browser. I'm a bit stumped. But I have found one way to alleviate the problem slightly, by limiting apt to not try...

This is not a bug in the Zabbix repo. It is the default way APT works - always trying to download at least the "en" translation package, but Zabbix does not provide one. You can tune apt-get to never try fetching ANY package translation files (assuming you are happy with english OS): # cat...

Hi all, recently I've been seeing quite a lot of E-Mails with error reports like this: Reason: 2018-01-17 06:29:17 INFO: pum is called with arguments: ['--list', '--repo-info', '--json'] 2018-01-17 06:32:09 ERROR: W:Failed to fetch...

Hi Igor, thanks for that idea, I applied it yesterday at 2 servers with this problem. This morning I did not see that problem. Thanks!

I'm running Debian 8 and Plesk Onyx 17.5.3 #37. I have noticed this problem on more than one machine: The OS-PHP FPM pool is empty, since I now only use PHP7.0 and 7.1. When I do a manual call of apt-get upgrade the output looks like this: Setting up php5-fpm (5.6.33+dfsg-0+deb8u1) ...

Hi Igor, thanks for question. Here are some articles which document /etc/postfix/postfix_default.pem within their text: How to generate custom self-signed SSL certificates and apply it to Postfix Unable to send mail using STARTTLS authentication: 4.7.0 TLS not available due to local problem...

Hi all, up until about a couple of months ago, in /etc/postfix/main.cf it said: smtpd_tls_cert_file = /etc/postfix/postfix_default.pem smtpd_tls_key_file = $smtpd_tls_cert_file Since recently this has changed (Debian 8.9), on the last 2 servers I installed it reads...
