我正在使用PHP邮件,我有以下标题:
MIME-Version: 1.0
Content-Type: text/html; charset=UTF-8; format=flowed;
Content-Transfer-Encoding: 8Bit
X-Mailer: Pressflow
Errors-To: some@email.com
Return-Path: some@email.com
Sender: some@email.com
From: Some Email <some@email.com>
X-SMTPAPI: {"category":"key:some_key"}
如果some@email.com是合法的电子邮件,但我不会在此透露......
有没有办法修改此标题,以便我的邮件不会被发送到Outlook中的垃圾邮件文件夹?
