您需要检查的第一件事是您是否能够快速连接到邮件服务器。



telnet到邮件服务器的端口25（您尝试发送邮件的端口）。如果需要花费太多时间，请联系管理员以获得进一步的帮助。



有很多因素可能会使邮件发送速度变慢，如防病毒程序检查或网络速度。

The very first thing you need to check is that whether you are able to connect to the mail server quickly.

telnet to port 25(port which you are trying to send mail) of the mail server. If it takes too much time then contact your administrator for further help.

There are many factors which may make the mail sending bit slower like Anti-virus program checking or network speed.
