PHP Mail gets blocked by spam filters
am 03.09.2007 18:25:31 von jason.m.hoHello,
I need to be able to send email in PHP without it getting filtered by
spam filters. Gmail usually filters all email sent using the "mail()"
function. I've looked on the forums, and am using the function below.
However, it seems to display alot of the meta data inside the email
itself. Is there something I'm doing wrong? Does anyone have any
suggestions/example that will send a well-formed email (with all the
meta data in tact)?
Thanks in advance,
