网站搬家到万网也遇到了一些小问题，搬家的过程还算顺利，但是也遇到了一点小问题，邮件回复功能又失效了。上网查询了一下，需要使用fsockopen函数。但是WordPress的SMTP默认发送方式为steam_connect_client而非fsockopen,所以需要打开/wp-include/class-smtpp.php 200-209行左右，将
$socket_context = stream_context_create($options);
$this->smtp_conn = @stream_socket_client(
$host . ":" . $port,
$errno,
$errstr,
$timeout,
STREAM_CLIENT_CONNECT,
$socket_context
);
这段改为
$this->smtp_conn = @fsockopen($host,$port,$errno,$errstr,$timeout);
就行了，当然前提是万网虚拟主机PHP.ini设置那里要保证fsockopen函数是打开的。

wordpress4.3已变成273-297行
if ($streamok) {
$socket_context = stream_context_create($options);
//Suppress errors; connection failures are handled at a higher level
$this->smtp_conn = @stream_socket_client(
$host . ":" . $port,
$errno,
$errstr,
$timeout,
STREAM_CLIENT_CONNECT,
$socket_context
);
} else {
//Fall back to fsockopen which should work in more places, but is missing some features
$this->edebug(
"Connection: stream_socket_client not available, falling back to fsockopen",
self::DEBUG_CONNECTION
);
$this->smtp_conn = fsockopen(
$host,
$port,
$errno,
$errstr,
$timeout
);
}
