Email to PHP app piping issue with bcc

[wshost]

Hi guys, I have quite a serious issue I'm trying to figure out. I forward all incoming email to a PHP app we wrote that processes it. This is how it works:

1. All incoming mail is piped to our PHP app.
2. Our PHP app reads the headers to:/cc: (attemps to read bcc: also but they never exist on bcc's) to find out what address it was sent to at our domain.
3. Our app processes the email differently based on the address it was sent to via an algorithm.

We use to have a forwarder for each possible address that when piped would pass a value to our script, and it would react based on that value. Now we have an extremely large number of possible addresses to work with and it makes more sense to forward all incoming mail to the app and deduct what address it was sent to. It works perfect if the email is in the to: or cc: headers, but if it is bcc:'d it breaks.

So, my question is: Is there any way to pass the email address to the script when piping the email? Seems the only way my script will be able to tell what incoming bcc'd addresses are is if the mail server tells it. I wonder if there is some type of shell scripting that can be used such as | /path/to/app.php %emailaddress%

Thanks so much for your help on this!

In sendmail, %1 is the variable that's used by virtusertable to refer to the email address of the current email. I just tried a number of different ways to get Sendmail's aliases file to pass that to a PHP script and I was not able to get it to work. I tried all of the following:

tully: "|/usr/bin/php /usr/local/directory/mail.php %1"
tully: "|/usr/bin/php /usr/local/directory/mail.php "%1
tully: "|/usr/bin/php /usr/local/directory/mail.php?email=%1"

and a bunch more but %1 never seemed to get passed to the PHP script.

Here is a way you can get this to work in a pinch. First, here's how I configure Sendmail to pipe email to a script:

tully-script: "|/usr/bin/php /usr/local/mail.php"

You could pipe the email to another script that then includes mail.php like this:

tully-script: "|/usr/local/php /usr/local/tully.php"
steve-script: "|/usr/local/php /usr/local/steve.php"
tony-script: "|/usr/local/php /usr/local/tony.php"

And in that example, tully.php would say

<?
$email_address = "[e-mail]";
include("mail.php"); ?>

?>

Of course, the first option is better if you can get it to work because it will work for every address at your company and you won't need to keep adding new ones manually.

I don't think you need to do this as a shell script. There should be a way to get sendmail to pass the address to the PHP script but I couldn't find it. (Please let me know if you do).

Tried it with %1 but there was no substitution, the script got %1 back through ARGV. Is there a list of what can be passed from sendmail to a script like this upon incoming mail?

Thanks again.

Even though PHP is receiving the data, your question is: what can Sendmail pass to your PHP script so it's really a Sendmail question. Google sendmail aliases pass "php script" or something like that. I'm sure there are Sendmail manuals, forums, newsgroups, and web sites that can point the way but my PHP skills aren't going to help much here, sorry. Good luck.
