Connection timeout error in JSD while configuring incoming mail handler

[Pooja]

Hi All,

We are trying to configure an incoming mail handler, but we are getting below the attached error message.
We are able to ping the port and host from the terminal machine.
We have disabled the firewall
But our clients are saying that we can not disable the antivirus for security reasons and also they are able to configure one more incoming mail server without disabling antivirus
