推荐答案
检查以下几点:
1-检查该端口587是否在您的计算机上打开
2-检查您的防病毒软件是否阻止了与端口的连接
Check the following points:
1- Check that this port 587 is open on your machine
2- Check if your antivirus is blocking the connection to your port
您好，
阅读以上异常中的消息.
Message =无法连接到远程服务器"
Message =无法建立连接，因为目标计算机主动拒绝它173.194.79.109:587"
可能由于以下原因之一
您可能正在从可能已终止gmail连接的PC上访问gmail，即任一防火墙都可能阻止了您对gmail的访问.或连接可能已超时.
看看.
Hi,
Read the message in the above exception.
Message="Unable to connect to the remote server"
Message="No connection could be made because the target machine actively refused it 173.194.79.109:587"
It can be either due to the following reasons
Either u may be accessing the gmail from a pc to which the gmail connection may have been terminated ie either firewall may be blocking your access to gmail. Or connection may have been timed out.
Check it out.
查看异常消息，它清楚地表明无法建立连接，因为目标计算机主动拒绝了它173.194.79.109:587".因此，请尝试在服务器上为端口587启用入站和出站规则.

Hi,
Look at the exception message, it clearly says "No connection could be made because the target machine actively refused it 173.194.79.109:587". So try enabling inbound and outbound rules for port 587 on the server.
