It's really recommended to use Mailenable Pro instead of Mailenable standard Edition. There are many advantages for both users and administrators. Although we've heard that installing Mailenable pro with Plesk could be very difficult and at the same time risky, but we found it easy and beneficial!
First of all remember these notes:
It's recommended to install Mailenable pro, in the same folder with Mailenable.
After installing, you'll find that you can't add new email by using Plesk.
After installing all Mailenable ALL postoffices will be lost!
We wanted to install Mailenable pro in webmail, but it's possible to install Mailenablewebmail and mailadmin in to different websites. (You can select it during installation process). If the login page of Mailenable loads correctly but the labels have not been filled with correct strings, and you have already used Horde as a webmail, you should change application pool from plesk App to Mailenable App.
Besides, it's crystal clear that you must change webmail Content directory to Pleskdirectory\Mailenable\Bin\NETWebMail (if you wat to use .Net version of Mailenable webmail). It seems that psaserv and psacln should have read& execute permission in new installed webmail.
I should mention that after installing Mailenable pro you should reconfigure it, because there is no postoffice in mailenable administration panel ! Thanks to plesk you can use "%plesk_bin%\mchk.exe" --domain --domain-name=yourdomain
to add domain to the postoffice and add all emails that have been already created in Plesk.
Good to know :
1- In services section of Mailenable Pro, you'll find new services such as webmail. You can configure webmail in this section. for example : date and time , default encoding,... . You can remove default webmail or install it in new website!
2- you can login to webadmin if you have enough privilege. Inorder to make a user webadmin , just right click on post office and in web admin section, enable web administration section for post office. After that open users section of post office and make the user "admin".
