We have just upgraded Plesk from a 9.5.2 version to 10.0.1 in our cloud server with centos 5.4 64 bit.
We use postfix mail server as before, but since the upgrade mail forwarding and mail alias stopped working.
New mails keep on the first account without being forwarded to the second account as selected in Plesk panel.
New mails never arrive to the main mail account when sent to a mail alias account as selected in Plesk panel.
We haven't found strange entries in /usr/local/psa/var/log/maillog. Nothing about forwarding and alias.
Could you give us some idea about this issue?

Thanks in advance for your help.
