Subject of the email to be sent. Lines should not be larger than 70 characters. To counter-act this, replace these occurrences with a double dot. If outside data are used to compose this header, the data should be sanitized so that no unwanted headers could be injected. 27, repectively, additional_headers did not have mail header injection protection.

Therefore, users must make sure specified headers are safe and contains headers only. Never start mail body by putting multiple newlines. This can be set with the additional_headers parameter, or a default can be set in php. The From header sets also Return-Path under Windows.

This should be a last resort, as it does not comply with » RFC 2822. The additional_parameters parameter can be used to pass additional flags as command line options to the program configured to be used when sending mail, as defined by the sendmail_path configuration setting. For example, this can be used to set the envelope sender address when using sendmail with the -f sendmail option. For security reasons, it is recommended for the user to sanitize this parameter to avoid adding unwanted parameters to the shell command. It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.

Header injection protection has been addded for the additional_headers parameter. This means that multiple consecutive newlines are no longer allowed. 2 Sending mail with extra headers. 4 Sending mail with an additional command line parameter. The additional_parameters parameter can be used to pass an additional parameter to the program configured to use when sending mail using the sendmail_path.

Second, the custom headers like From:, Cc:, Bcc: and Date: are not interpreted by the MTA in the first place, but are parsed by PHP. As such, the to parameter should not be an address in the form of “Something “. The mail command may not parse this properly while talking with the MTA. This function opens and closes an SMTP socket for each email, which is not very efficient. For the sending of large amounts of email, see the » PEAR::Mail, and » PEAR::Mail_Queue packages.

So these parameters are safe against injection of additional headers. Otherwise you just created a potential spam distributor. Hopefully it is of some use. This executable is a standard, and emulated by other MTAs.

It only works because some systems will clean up your mistake. Here’s a small handy function I use to send email in UTF-8. OSX may not provide the same level of detail. Send mail with minimal requirements from email services. I was having delivery issues from this function to Gmail, Yahoo, AOL, etc. I used the notes here to figure that you need to be setting your Return-Path to a valid email to catch bounces. The domain in the email used in the -f option in the php.

That’s header field being used for spam checks. You should also use a domain key or DKIM. I used Cpanel to create my domain key which automatically used all lowercase domain names in the key creation. Com” option, my key was not accepted. There are many other factors that can contribute to mail not getting to inboxes, including your own multiple failed testing attempts, so I suggest you consult each site’s guidelines and don’t ask me for help. These are just the couple technical issues that helped my case. It really boils down to changing few directives in php.

550 Messages should have one or no Cc headers, not 2. Note that there is a big difference between the behavior of this function on Windows systems vs. Windows system, some MTAs will get a little upset. This is mostly unnecessary because qmail will ignore any additional To: headers injected by a malicious user. However if you have some strange mail setup it might be a problem.

The function returns false if the message fails validation or is rejected by qmail-queue, and returns true on success. Just a comment on some of the examples, and as a note for those who may be unaware. ONLY acceptable line break format in the headers, though is a little vague about the message body. I’ve run accross plenty of them that will exhibit “interesting” behaviours when this happens. A a sequence of ASCII characters ending with a . RFC 821 makes no distinction between header lines and message body lines, since both are actually transmitted during the DATA phase.
