I have not touched any configuration files and I let Plesk to do the config.
I read that perhaps this is a timeout issue, but I dont know for sure.
Any help is greatly appreciated.

Yes, there is timeout problem with postfix-queue and it should be completely fixed in Plesk 9.3
But as I see you have Plesk 9.0 version installed. I can recommend you upgrade your Plesk to latest available version where Postfix operation has been seriously improved.

sorry for my last post.
I installed Plesk about 15 days ago and used the last available installed from the downlad area. Then performed the updates in the Updates section.
My admin panel says: Parallels Plesk Panel version 9.2.3
If I click on Updates it says:
Parallels Plesk Panel 9.2.3 You have an up-to-date version
