Email Parser

I keep getting this error does not matter from what location I try to connect:

Error. No connection could be made because the target machine actively refused it

I tried with 2 different email addresses (different email severs and settings) , I also tried with gmail same result

those settings are working for my email client (thunderbird)

Any advice is really welcome

thanks

ok I finally found what it was, my local firewall was blocking the software silently no warnings at all
but I did not found earlier because the error message was misleading me, by saying that connection was being refuse by remote machine (email server)...
