X-Ray Mail Assistant

X-Ray Mail Assistant is an email header filter and POP/SMTP server switching tool. It runs as a local POP/SMTP relay server and scans your incoming and/or outgoing mail for user specified mail headers. Once it finds a match it can change the header, remove it, replace it or perform some other special modifications. In addition, the program allows you to set up multiple profiles for POP and SMTP servers and switch between them from the system tray.
Major objectives of X-Ray are:
To provide privacy by removing unwanted mail headers;
To make it convenient to switch between several different incoming and outgoing mail servers without reconfiguring your mail software;
To operate stably and unobtrusively.
X-Ray Mail Assistant is primarily intended to work with Rit Labs' email client "The Bat!," but will work with any email program that sends mail via SMTP and receives it via POP 3. If you are comfortable changing the server and port settings in your email client, this program won't scare you; on the other hand, if you don't know what port settings are, you should probably get help from your local expert.
