Plesk Qmail error – 451 qq internal bug (#4.3.0)

If you are getting error while sending email from your plesk server using outlook

Send test e-mail message: Your outgoing (SMTP) e-mail server has
reported an internal error. If you continue to receive this message, contact
your server administrator or Internet service provider (ISP).  The server
responded: 451 qq internal bug (#4.3.0)

To eliminate this problem, stop Qmail process and replace qmail-queue, qmail-local and qmail-remote with the qmail-queue.moved, qmail-local.moved and qmail-remote.moved accordingly:

# cd /var/qmail/bin
# cp -p qmail-local.moved qmail-local
# cp -p qmail-remote.moved qmail-remote
# cp -p qmail-queue.moved qmail-queue

Log rotation in plesk 8.x

November 13th, 2009 No Comments   Posted in Plesk

Some websites receive high traffic and, as a result, the apache log files grow very large, very quickly. By default, Plesk rotates logs every 2,025,139 KB (2GB). This is way too large for a virtualised server such as ours, which provides 10GB of precious disk space.

To combat this, I set up a regular log rotation in Plesk like so:

  • Log in to Plesk.
  • Domains > yourdomain.com > Log Manager > Log Rotation
  • Choose the log rotation condition.
