Hey all, putting this up for Misfit, and anyone else that wants to be\nrid of all posts by people that hide behind X-No-Archive in newsgroups. \nCame up in thread in nz.general a week or so ago and I'm too lazy to try\nto find the post again to reply to. Also should give you an idea of how\nto add a filter on any other custom header in thunderbird.\n\nHow to set up an XNoArchive filter:\nTools Menu -> Message Filters. Select the newsgroup you want to apply\nthe filter to in the drop-down list at the top. Once that is doen,\nclick the New Button.\n\nA dialog titled "Filter Rules" appears. Place a name for the filter in\nthe top text box eg "XNoArchive"\n\nIn the middle section the first drop-down list has Customise as its last\nentry, click this and a new dialog box "Customise Headers" appears. \nEnter the text "X-No-Archive" in the top text box without the quotes.\nMake sure you enter it exactly, with hyphens and not underscores and no\nspaces. Im not sure if it is case sensitive so to be safe make sure the\ncase is correct. Click the "Add" button. X-No-archive should now be in\nthe larger text area. Click "OK"\n\nThis should put you back in the Filter Rules dialog. Change the first\ndrop box in the middle section from Customize to the X-No-Archive option\nthat is now present. Change the next box to "contains" and then enter\n"yes" into the blank text box to the right of it. change the first (or\nonly) drop-down in the bottom section (perform these actions" to "Delete\nMessage". Click "OK". \n\nYou should now be free of messages from all posters with the\nX-no-archive header set in that newsgroup. If you need to set it up for\nseveral groups you wont need to create the new header in the Customise\nheaders dialog.
