Why a large message failed to send

When you use Foxmail to send a message, a few KB of small messages can be sent normally, but if it is a slightly larger message, such as dozens of KB, sending a progress bar forward half, it will stop unable to send.

The above failure, generally due to network instability caused by the data can not be transmitted correctly caused. To solve this situation, you can use a gateway or proxy server to avoid this situation by connecting to the network in a LAN, instead of using a "shared connection" approach. Also pay attention to is not caused by the virus, to timely anti-virus.
