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
If you face any problems replaising these files, you can stop thses processes forsible and then try to replace them:
# killall qmail-remote qmail-queue qmail-local
Make sure that the permissions and ownersips are right:
# ls -la qmail-queue qmail-local qmail-remote -r-xr-xr-x 1 root qmail 44060 Jun 13 2006 qmail-local -r-s--x--x 1 qmailq qmail 15784 Jan 26 14:06 qmail-queue -r-xr-xr-x 1 root qmail 43364 Jun 13 2006 qmail-remote

Guys, you are the best
I run a dedicated server, my sys admin and AT&T top IT were trying to figure why my mail when I shifted to AT&T Uverse was dead!
I G and found you, applied the fix
IT WORKS!
Thanks
Kind regards
Henry
you’re welcome
This is excellent! How did you learn this stuff?
Thank you thank you! I removed Parallels Premium Antivirus and could no longer send or recieve email, and rebuilding the qmail settings wasn’t helping. This worked perfectly!
