I've used formmail.php twice before (on a different host) and have been very happy. I wanted to use it for a different client and the host told me the following:
We do not allow this script to be run on our servers. If you attempt to run it, you will receive a "Forbidden" error. We do not allow "Formmail" due to the high number of Spam exploits. If you want to run this script, you have two choices:
1) The one we recommend the most. This is to use our customized version of this script. We call it "FormNewMail". It can be found in the "Online Support Pages" part on XXXXX.
2) You will just need to change the name of the script to something other then "Formmail".
NOTE: If you choose run an odd version of Formmail, and change the name of the script and it gets exploited for Spam, we will delete your account for a Terms of Service violation.
How can I tell them that your formmail.php is not the spamming type? I thought there was a page on the site that that described this, but I could not find it.
