I have not used FTP access in a while, so I do not know exactly when it broke, but I have known for a while that only SFTP kept working after Plesk broke FTP. Now I have to do a Wordpress update in a subdomain and can find no way to do it, because in the subdomain neither FTP nor SFTP works...

OS: Debian 6.0.6 Panel version: 11.5.30 Update #11 (updated from 11.0) The two services "Courier IMAP server" and "Courier IMAP server with SSL/TLS support" are not running, and trying to start them has no effect. Is this a known defect? Is there a workaround? Do you need more information...

I have migrated to a new server running Plesk 11.0.9 with postfix 2.7.1-1+squeeze1. On the old server email worked perfectly well, but on the new one I have this problem. When I try to send mail from Thunderbird or K-9, I receive an error mail back, essentially with the message: 451 4.3.0...

Most of my mail addresses have been migrated from earlier Plesk versions some time ago. Unlike earlier Plesk versions the mail address owners cannot change their passwords. When they try to log on to the Plesk control panel with their mail addresses and mail passwords, they get the error...

I am running Plesk 10.3 with postfix, but the defect has, as far as I can remember, always been there. I am currently more concerned with the whitelists, but the blacklists also do not work. I have disabled the antivirus function, presumably DrWeb. I also do not use SpamAssassin. I rely on DNS...

Watchdog did not work. I found a hint to uninstall, then reinstall it, so I removed Watchdog through Plesk (version 10.2) on the Modules page. Then I tried to reinstall it with Plesk. In Plesk 9 this was done through the Update page, but in Plesk 10 it seems to be impossible to reinstall...

Using the Plesk Updater and trying to get the latest updates, I receive this error: Error: error during prepare patch plesk-9.5.2~patch2 The MD5 checksum of the /root/psa/PSA_9.5.2/microupdates/MU2/dist-rpm-SuSE-10.1-i386/sw-engine file does not match the value specified in the...

I understand that greylisting means that emails are, at first, rejected and only accepted at the second delivery attempt. This, however, means that emails are delayed, possibly by hours, depending on the time the sender takes before retrying. Is this delay always there for all emails or does...

I use a number of DNS blacklists in the Plesk mail server settings (with qmail), and altogether they work exceedingly well. However, I would like to know which of the blacklist blocked how many emails. Any idea in which log file on the server I can find this information?

Mail users trying to deliver email via Qmail's SMTP server experience the following error if they don't have an SPF record in their DNS. '554 mail server permanently rejected message (#5.3.0)', Port: 587 The SMTP server apparently does an SPF check on an authenticated user delivering...

Something ever computer science student learns pretty early is the concept of orthogonality. What is meant is that, if a computer program has two features, then it is not enough that one feature works and the other also works. The requirement is that both functions still work when they are both...

The host name of my server is india155.server4you.de, but the file /var/qmail/control/me contains only the incomplete name: india155 This leads to certain other mail servers rejecting all my outgoing mail because of an improper HELO, because they sensibly check the name against DNS and IP...

This is Plesk 9.0 on SuSE Linux 10.1. It took me and my co-admin a number of hours to nail down a nearly intractable error we had after upgrading from Plesk 8.6 to 9.0. Users of certain domains could no longer send any email. It turned out that apparently all users whose domains have no SPF...

I have several domain aliases that use mail. The main domain has domainkeys enabled, and the domainkeys have been tested and work fine. However, for the domain aliases the server does not add a domainkey signature to the headers of outgoing mails. Domainkeys are working only for one domain...

Please help me with a fundamental issue of understanding. I'm running a Plesk-based server on SuSE Linux 10.1, but would like to update the operating system to version 11 or use a different one altogether, like Ubuntu. Are all Plesk settings independent of the operating system, such that I...

When an SMTP user authenticates himself with his username and password, his IP address is still checked against the DNS blacklists. This prevents most users from sending any mail, if the blacklists contain a policy blacklist that checks for dial-in addresses such as DSL lines. The best example...
