Unable to read data from the transport connection: net_io_connectionclosed.

Hi @farid_sdt

Can you tell me about any customizations you might have made to the exim configuration in the past and exactly how you reset the exim configuration?
hi,
there were some changes that i didn't know what they were, some things have been disabled as wrong ( for example Require clients to connect with SSL or issue the STARTTLS command before they are allowed to authenticate with the server. ).

i tried reseting exim configuration using the feature available in exim configuration manager. i tried the following options one by one:
option 2
option 3
option 5
option 1

none solved the problem.
