hMail Server configuration

Hi Team,

We have installed hMail Server at our Network for SuiteCRM.
We can able to send the test mail from Suite but while connecting through incoming email (IMAP) we are getting connection refused error.

“Can’t connect to *****,143: Refused. Please check your settings and try again”

Please note that, from Microsoft outlook client send and receive working properly.

Please suggest.

Regards,
Ashish

Same issue here. Sugar CE used to work.
