Simple mail() format question

[tomhilton]

Hi,

I have a function that allows a sender to send mass email to other memebers of a website. It pulls valid emails from a mysql database and formats and sends the message.

Problem is if the sender has no valid email address of his own. The output shows the "From" portion of the additional headers parameter as:
"From: Member [e-mail]".

Here is basic script:
if ( !empty($sender_email) ){
$header="From: $sender_name <$sender_email>";
}else{
$header="From: $sender_name";
}

How can I format the "From" section to not include the [e-mail] for those people without email addresses?

you cant, it must send a email address in the from, if you dont supply one it uses the default, basically you should make it a requirement that people supply there own email addy if they want to send emails
