I've used this class extensively and not had any trouble with email being rejected as spam by Yahoo, or anyone else.

blocks|key|797858|text|'sendmail‘(在PHP+mail()函数下)也可能需要额外的参数。如果返回头(比如Return-Path)没有按照您设置的值进行设置，那么可能需要使用第五个mail()参数。示例：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|797859|mail('recipient@domain.com',+'Subject',+$mail_body,+$headers,+"+-f+sender@domain.com");|code-block|syntax|javascript|797860|有一些进一步的证据表明，真正的普通sendmail可能在这方面存在问题！希望你在目标服务器上有'postfix‘作为PHP的底层mail()支持。|797861|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

There is also the possibility that 'sendmail' (which is underneath the PHP mail() function) needs extra parameters. If you have a problem with return headers (such as Return-Path) not being set with what you set them to be, you may need to use the fifth mail() parameter. Example:

<pre><code>mail('recipient@domain.com', 'Subject', $mail_body, $headers, " -f sender@domain.com");
</code></pre>

There is some further evidence that true vanilla sendmail may have problem with this! Hopefully you have 'postfix' as PHP's underlying mail() support on your target server.

In addition to <a href="https://stackoverflow.com/questions/161048/what-do-i-need-for-a-compliant-email-header#161052">Ted Percival's suggestions</a>, make sure that the IP address the email is coming from is a legitimate source for email according to the <a href="http://www.openspf.org/" rel="nofollow noreferrer">SPF record</a> of site.com. If site.com doesn't have an SPF record, adding one (which allows the IP address in question, of course) may help get the emails past spam filters.

And if absolutely do need to use HTML in your email, make sure that you also include a plain text version as well; you'd use the content type of "multipart/alternative" instead of "text/html".

blocks|key|3927819|text|Ted的建议很好，Tim的也一样，但我能够可靠地将电子邮件发送到Yahoo/Hotmail/等的唯一方法是使用PEAR电子邮件类。尝试这些&(假设您的服务器是正常的)，我几乎可以保证它会工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3927820|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Ted's suggestions are good, as are Tim's, but the only way I've ever been able to reliably get email through to Yahoo/Hotmail/etc is to use the PEAR email classes. Try those &amp; (assuming your server is OK) I can pretty much guarantee it'll work.

blocks|key|5337506|text|泰德和蒂姆有很好的建议。Shabbyrobe也是。我们使用PHPMailer，在垃圾邮件过滤器方面没有任何问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5337507|需要注意的一点是，如果您使用的是MIME格式，许多垃圾邮件过滤器将被视为没有针对您的文本版本。您可以自己添加所有的头文件和文本版本，也可以让PHPMailer或PEAR邮件库为您处理。有一个文本版本可能会有帮助，也可能没有帮助，但这是一个良好的实践和用户友好。|5337508|我知道你的代码样本只是一个样本，但值得说的是:永远不要把用户提供的数据放到你的邮件头中。确保验证它是您期望的数据。把一个php邮件脚本变成一个开放的中继是很容易的，而且没有人愿意这样做。|5337509|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Ted and Tim have excellent suggestions. As does Shabbyrobe. We use PHPMailer and don't have any problems with spam filters.

One thing to note is that many spam filters will count NOT having a text version against you if you are using a MIME format. You could add all of the headers and the text version yourself, or just let PHPMailer or the PEAR mail library take care of that for you. Having a text version may or may not help, but it is good practice and user friendly.

I realize that your code sample is just that - a sample, but it is worth saying: Do not ever just drop user provided data into your mail headers. Make sure you validate that it is data you expect. It is trivial to turn a php mail script into an open relay, and nobody wants that.

blocks|key|3927874|text|检查rfc+822和rfc+2045的电子邮件格式。我发现python的Email类非常容易使用。我假设php的PEAR也做了同样的事情(根据之前的邮件)。此外，标题和正文由"\r\n\r\n“分隔，不确定您的代码是否会自动插入，但您可以尝试将其附加到标题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3927875|我不认为DK/SPF可能是必要的(因为有很多out服务器没有DK/SPF支持)。可能有很多因素会导致它被阻止(至少有10K种不同的标准和方法..p0f、灰名单、灰名单、黑名单等)。确保你的电子邮件格式正确(这会有很大的不同)。查看为您生成完整头文件的库。这样你犯错误的机会就最少了。|3927876|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Check rfc 822 and rfc 2045 for email format. I find python's Email class really easy to work with. I assume php's PEAR does the same (according to earlier mails). Also the header and the body are separated by a "\r\n\r\n", not sure if your code automatically inserts that, but you can try appending that to the header.

I dont think that DK/SPF might be necessary (since there are lots of webservers out there without DK/SPF support). There can be alot of factors that might be causing it to get blocked(atleast 10K different criterions and methods.. p0f,greylisting,greylisting, blacklisting etc etc). Make sure that your email is properly formatted(this makes a BIG difference). Look into libraries that generate the complete header for you.. that way you have least chances of making any mistake.

Adding a SPF record is very easy. You should try.

This one is for dreamhost plus googlemail
You should also ad you webserver ip address (in my case, the line before googlemail)
The last line tells the server to do a soft reject (mark as spam but don't delete) I'm using it instead of "-" (delete) because google documentation says so :-)

It's a TXT record
v=spf1
ip4:64.111.100.0/24 ip4:66.33.201.0/24 ip4:66.33.216.0/24
ip4:208.97.132.0/24 ip4:208.97.187.0/24 ip4:208.113.200.0/24 ip4:208.113.244.0/24
ip4:208.97.132.74 ip4:67.205.36.71

I am trying to send an email from a site I am building, but it ends up in the yahoo spam folder. It is the email that sends credentials. What can I do to legitimize it?

<pre><code>$header = "From: site &lt;sales@site.com&gt;\r\n";
$header .= "To: $name &lt;$email&gt;\r\n";
$header .= "Subject: $subject\r\n";
$header .= "Reply-To: site &lt;sales@site.com&gt;" . "\r\n";
$header .= "MIME-VERSION: 1.0\r\n";
$header .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$phpversion = phpversion();
$header .= "X-Mailer: PHP v$phpversion\r\n";
mail($email,$subject,$body,$header);
</code></pre>

What do I need for a compliant email header
