solution:

On Mailenable SMTP Service ->Properties->Inbound->Access Control->Granted Access ->All

You have to open the mailenable application on the web server or email server

And allow access for all IP addresses in the SMTP service.

Most likely the IP address of the sender is blocked

 

 

In Mailenable->Servers->localhost->SMTP Services and Connectors

then SMTP ->Contextmenü->Properties->Inbound->[IP Address Connection Restrictions]->Access Controll

 

 

then Access Control

->by Default: Granted Access

->Exept those listed below: empty

Mobile
