Description:
------------
Our old API is using "mail" function to send e-mails. When it needs to attach files, it creates the mail body and specifies it as a "header" parameter for the "mail" function. With PHP 4.3.2 on Windows XP mail send stopped working. The mail received had all of the "CRLFCRLF" ("\r\n\r\n") strings converted to CRLF ("\r\n"), in other words some kind of header parsing was done by mail function."CRLFCRLF" is absolutely necessary for "message/rfc822" format. Maybe it looks a bit odd to use "mail" function for that, but BEFORE it was working for years, and NOW it doesn't. The "continuity of versions" law is broken.

Problem disappeared with PHP4.3.3RC1.

Today I have downloaded PHP4.3.3RC1. Problem has not disappeared. My MailList module converts attachments in mail into BASE64. And problem is that the first 76-symbols line of the BASE64-encoded attachment is cut! Even CRLFCRLFCRLF is being converted into CRLF!

The $header parameter is for headers.
The $message parameter is for the message (including multipart content).

Using mail() to put content in the $header parameter is not in accordance with its intended use.

By using a function incorrectly, you should not be surprised to find that it behaves unexpectedly.

Last comment disappoints me. I don't want to believe that PHP source code is a training base for boy-scouts."Continuity of versions" is not an empty sound. Dear pollita@php.net: If function was working for years, and then stops working just because someone fixes it up to his understanding of it, forgetting that there are tonns of code in the world using that function, then it must not be a PHP - Web Development Solution - but experimental solution for young C programmers.
Cheers

Regardless of how disappointed you may feel, you were misusing the API.

A number of changes have been and are being made to newer versions of the win32 mail command to protect against SMTP injection attacks and help prevent your scripts from being used as an open relay for spam.

If you are unhappy with the way that PHP is being developed, you can always:

o patch your local sources
o contribute a patch that is both safe and allows what you want to do.
o pay one of us to do it for you
o stop being so negative, hold your tongue and fix your script.
