Maildrop opene d for exclusive access by another user.

在项目中使用邮箱获取邮件时:Maildrop opene d for exclusive access by another user.

解决方法:
设置pop的session超时时间:POP_SESSION_TIMEOUT = 10

# 连接到POP3服务器:
server = poplib.POP3_SSL(pop3_server, pop3_server_port)
# 增加POP3服务器的POP_SESSION_TIMEOUT 进行解决
server.POP_SESSION_TIMEOUT = 10
