To Whom It May Concern: We upgraded Plesk panel last evening from 10.3.1 to 10.4.4 Update #21, last updated at Mar 8, 2012 04:50 AM No errors were reported and the update said successful. When we looked at the component versions this morning, we noticed that MailEnable Standard is still showing version 4.26. According to the release documentation it should have been updated to version 6.0. The update / upgrade procedure is grayed out in the Plesk panel because it says all components are up to date. Any specific suggestions how to manually update MailEnable without damaging Plesk would be appreciated.
