A reply to my first posting about X- records. ----------------------------Original message---------------------------- X-anything is supposed to be ignored, basically. If you have some peculiar function you want to implement on your UA/MTA, you can look for particular X-tags. Listserv generates the X-To's when the original mail is sent to other recipients other than the list name. Listserv also communicates between peers using X-tags in the headers. X-tags are passed in transit, but are only meaningful to specific UAs/MTAs. /Jeff/
