Mail Headers

Anyone know of a place that I could get a list of all of the headers I can send along with my email? I need to be able to send a header along with my emails that tells the server I'm sending it to where to send the bounce notification if the address is not valid. Thanks for any info! --Joe /*****************************\ * Joe Stump * * www.Care2.com * * Office: 650.328.0198 * * Extension: 122 * \*****************************/ http://www.miester.org/Joe/Stump/Joe_Stump_resume.html -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GB/E/IT d- s++:++ a?
