  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

One Mailbox cannot sending Mails

Stefan Becker

Basic Pleskian
Hi,

i have one Mailbox on my server, which i cannot sending mails. I tested it with Outlook and Horde.

For Example, i see this error at the Maillog:

Code:
Jul 14 22:12:13 gaius postfix/cleanup[12194]: 2F653402A6: milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 5.7.0 The message could not be sent. You are not allowed to use sendmail utility.; from=<user@server1.local> to=<user2@server.local> proto=ESMTP helo=<gaius.stefanshome.com>

I delete this Mailbox, but after a time, i have the same problem again. On the Plesk Webinterface there is no problem logging with the outgoing spam protection.

Have anyone an idea?

Stefan
 
This message should appear neither when using Outlook, nor Horde (since they use SMTP). This means that either you're looking at the wrong log line, or your mail subsystem configuration is slightly wrong.
