helpdesk - "not email config"

[cao]

I config the email on Setting --> System configuration --> Setting
Main options -- email setting ( Registrations and Lost passwords email sender, Help Desk email and Sender email address for alert messages )
I filled the info for all three fields -- Save changes and clear cache.

Still received the message -- "not email config" on the helpdesk form after I click submit.
Thank

Hello,
How to configure the email.
Any other setting for the email.
I am using hMailServer as my mail server.
Thank You

I will try to reconfigure hMailServer.
That could be the problem
