发送过程邮件内容丢失

部分丢失，不知道怎么回事$from='"=?utf-8?B?' . base64_encode($_SESSION['LoginNAME']) . '?="<' . $_SESSION['MailAddress'] . '>';
  $subj =$tilte;// "my test subject";
  $msg  =$content;// "this is the email body";

  $endtime=$endDateTime;

  $cal_uid = "{" . uniqid(mt_rand(), true) . "}";
  $cal_uid = "{" . date('Ymd').'T'.date('His')."-".rand()."@mydomain.com}";  $cal_msg =

请求头加上content-length试试
  $header .= "From: " . $from . "\r\n" .
          "MIME-Version: 1.0\r\n" .
           "Content-Type: text/calendar;method=REQUEST\r\n".
           "Content-Length:".strlen($content);?>

mail函数执行之前我看了看$msg还正常，发完之后看邮件内容就少了

是不是$msg里有一些字符导致解析不正确?

你把$msg换成很长的一串英文字符，没有任何特殊符号的那种,先把长度设成和$content一样多，如果可以发送成功，说明很有可能是一些特殊符号的问题。for($i=0;$i<strlen($content);$i++){
$msg .= "a";
}

那就是说发送的内容过多，给截断咯
你的$msg多少字节阿？

我测试随便输入，1000字左右，就剩二三十的样子，我用outlook发不用这个程序发都能正常显示，我想应该是mail函数发送过程中出的问题

php发送邮件多用开源类库phpmailer，你试下用这个。

我先试试以上方法，谢谢
另外我本地机不能测试，老是说SMTP server response: 530 5.7.0 Authentication required每次测试都拿到服务器上比较麻烦，这个问题怎么解决啊，前段时间没这个问题，自从公司服务器换了端口就不行了，把25换成别的了

php.ini里不是有端口设置么？换了端口后,你有改么？[mail function]
; For Win32 only.
SMTP = localhost ;改成正确的邮件服务器地址
smtp_port = 25 ;改成正确的端口,默认为25

都改了，我从phpinfo（）里看到的对应的php.ini文件，应该没错啊不知道哪个地方的原因

晕，呵呵,测试半天还是特殊字符的问题啊？是不是邮件内容，也就报文内存在\r\n?
邮件内容中最好不要出现\r\n换行符，具体查阅下rfc821协议.
可以把$msg中的\r\n换成<br/>试试。

把换行符都去了，让它在邮件里显示的内容变成一段了，这样好像改变了原文的样子，换成 <br/>就不会改变了吧？另外，我发送邮件，发送到outlook2007没问题，发到outlook2003就有问题，源代码竟然出现在邮件内容里了，老板让解决这个问题，我没头绪，真要命了foolbirdflyfirst 您再给指点指点吧？！

foolbirdflyfirst 哪儿去了呢？还有其他高人吗？

1.$cal_msg里的内容，每一行后面加上一个\n作为分割，要不挤在一起，发出的就是一封普通outlook mail了,而不是outlook calendar mail
$cal_msg =
"BEGIN:VCALENDAR\n
PRODID:-//Microsoft Corporation//Outlook 11.0 MIMEDIR//EN\n
VERSION:2.0\n
METHOD:REQUEST\n
BEGIN:VEVENT\n
..
"
2.$msg = preg_replace('/\r\n/','\n',$msg);//\r\n一定要替换掉，替换成\n估计就可以换行了。

哎呀，你可有反应了
outlook2003收到的内容是这样的Return-Path: <[email protected]>

不是
加个\n就能解决了的
还是这样
foolbirdflyfirst您再帮我想想办法行吗

这个就是因为你发送过去的outlook日历邮件不符合outlook邮件的解析标准，它把你发的东西解析成一封普通邮件了。
我本地测了下你的例子，是可以成功发送的。在本地搭建的winmail server,outlook2003
具体代码原封不动如下,发送后outlook日历2009.09.23将多出一份会议记录$from='"=?utf-8?B?' . base64_encode($_SESSION['LoginNAME']) . '?="<' . $_SESSION['MailAddress'] . '>';
  $subj =$tilte='jet';// "my test subject";
  $msg  =$content="hello \r\nworld!";// "this is the email body";
  $location=$address;//
  $starttime="20090923T131415Z";
  $endtime="20090923T151617Z";
  $header = 'To:' . $toname .  "\r\n";
  $header .= "From: " . $from . "\r\n" .
          "MIME-Version: 1.0\r\n" .
           "Content-Type: text/calendar;method=REQUEST";  //Various ways to creat a new, random UID
  $cal_uid = "{" . uniqid(mt_rand(), true) . "}";
  $cal_uid = "{" . date('Ymd').'T'.date('His')."-".rand()."@mydomain.com}";  $cal_msg =

//mail服务器为localhost,端口25
if (mail("[email protected]", $subj, $cal_msg, $header, "")) {
             }

内容是
=====
hello
world有效换了行。
