  • Plesk 9.5 for Windows


SmarterMail 6 FREE is used as a mail server, and Atmail as a webmail.
Logging in to webmail fails with the following error:

Cannot login in, there is an error. Check login details and mail-server responding.


SmarterMail 6 detects if it is installed on the same server as Plesk, and switches from the FREE mode to LITE automatically. The LITE mode does not support IMAP.


Install a commercial license of SmarterMail, or switch to the Horde webmail client.
