in my website i’ve a PHP script that automatically mails to my customers a confirmation about the order.
My website’s domain is registered to a company that hosts my website too.
I have a lot of problems to send e-mails using mail() function to some e-mails accounts … a lot of my users contact me saying that they have never received my automatic e-mail! So this is a very big problem!
The accounts, that give me more problems, are comcast.net, uol.com, mchsi.com and others! I’ve contacted the support center of these e-mail service providers asking for removing my ip from the block list too.
The header of the e-mail looks like this:
$header = "Sender: $from_mail\n";
$header .= "From: Account <$from_mail>\n";
$header .= "Reply-To: Account <$from_mail >\n";
$header .= "Content-Type: multipart/mixed; boundary=$mixed_boundary\n";
$header .= "Mime-Version: 1.0\n";
$header .= "X-Mailer: PHP/".phpversion()."\n";
$body = "\n--$mixed_boundary\n";
.
.
.
.
$body .= "\n\n--$mixed_boundary--";
mail($to, $subject, $body, utf8_encode($header), "-f$from_mail");
There is something that I can try to avoid this problem?
Someone knows where can I look to know what is the IP address of the server used to deliver e-mails thought the PHP mail() function?
Thanks in advance for your replies!!!
Hi,
still today some e-mail provider service such as Comcast, continue to block my IPs addresses saying that my mail server sends spams … I requested the removing from the blocklist, but their system continue block them! I don’t know what else can I do … I’ve followed your suggestions and the code look like this:
$md5 = md5(date('r', time()));
$mixed_boundary = "PHP-Mixed-$md5";
$alt_boundary = "PHP-Alt-$md5";
$header = "Sender: $from_mail\r\n";
$header .= "Errors-To: $from_mail\r\n";
$header .= "From: account <$from_mail>\r\n";
$header .= "Reply-To: $from_mail\r\n";
$header .= "Content-Type: multipart/mixed; boundary=$mixed_boundary\r\n";
$header .= "Mime-Version: 1.0\r\n";
$header .= "X-Mailer: PHP/".phpversion()."\r\n";
$body = "\n--$mixed_boundary\n";
$body .= "Content-Type: multipart/alternative; boundary=$alt_boundary\n";
.
.
.
.
$body .= "--$mixed_boundary\n";
$body .= "Content-Disposition: attachment filename=\"...\"\n";
$body .= "Content-Type: application/octet-stream; x-unix-mode=0644; name=\"...\"\n";
$body .= "Content-Transfer-Encoding: base64\n";
.
.
.
.
$body .= "\n\n--$mixed_boundary--";
mail($to, $subject, $body, utf8_encode($header), "-f$from_mail");
Suggestions?
Thanks again!
Your message headers are not valid according to RFC2822 Internet Message Format.
From 2.1 General Description:
As I pointed out in my comments, the reason why your email may work with most mail servers anyway is that they may be liberal in what they accept. There may be some mail servers, however, that will discard your messages since they don’t comply with RFC2822.
EDIT: Although the use of "\r\n" is advocated in the PHP documentation for the mail() function, there is some debate about whether that’s really the right thing to do.
The mail() function will communicate with the local sendmail(8) command (or whatever is configured in sendmail_path), and the line endings may be processed differently depending on what mail transfer agent implementation is used. From what I understand, sendmail(8) should be OK with "\r\n", but qmail(7) for example will replace "\r\n" with "\r\r\n", which will probably break the message.
This all happens before the email is delivered to its final destination, so it may be easily tested whether the line endings are processed properly by sending one’s self an email message constructed with "\r\n" and by verifying that all headers are present.
