RC4 email

This module provides graceful email obfuscation to protect email addresses from harvesting bots on mailto links generated by the Drupal l() function by obfuscating email addresses found in mailto links and its link text. A RC4 ciphertext of the original email address are saved and is later decrypted and reinserted back to HTML by Javascript, providing a transparent experience to sites where a majority of users are using a Javascript-enabled browser, at the same time prevents non-Javascript capable bots (which at the time of writing, are the majority of the bots out there) from harvesting email addresses.

We make good use of the RC4 stream cipher for saving and restoring plain text email addresses, hence "RC4 email".

X-Originating-IP email header

Add the X-Originating-IP header to all outgoing emails to assist with investigation of the sources for spam and unsolicited bulk email.

A standard Drupal install sends email as if it was originating from the web server when in fact, the email originated with a person's web browser. Use this module to include information in the outgoing email header about the IP address of the person who submitted a request to a Drupal website.

Without this module, Drupal effectively becomes an anonymizing service because the standard email headers will have the email origin listed as the web server IP address instead of the user elsewhere on the Internet. By using the information from X-Originating-IP, you can track down individuals who send undesirable communications through contact or webforms.

X-Originating-IP: [xxx.xxx.xxx.xxx]

The originating IP is based on the ip_address() Drupal API function.

If Drupal is behind a reverse proxy, we use the X-Forwarded-For header instead of $_SERVER['REMOTE_ADDR'], which would be the IP address of the proxy server, and not the client's. The actual header name can be configured by the reverse_proxy_header variable.
