It may contain more Message-IDs from the thread.

Having it in those headers in the messages you post means you are replying to a thread containing the content, not that you posted the content. Besides, unless the user has specifically set their mailer to do something different, the bit after the "@" often defaults to the domain in their email address. > So, how to deal with this behavior?

Only if for each thread you use a unique subject line that will never be repeated, and you can guarantee that everybody reading the threads only ever receives email from people who do the same. - -- Best regards MFPA mailto:2014-667rhzu3dc-lists-gro...@riseup.net When duty calls...hang up immediately -----BEGIN PGP SIGNATURE----- iPQEAQEKAF4FAlR74ZpXFIAAAAAALgAgaXNzdWVyLWZwckBub3RhdGlvbnMub3Bl bnBncC5maWZ0aGhvcnNlbWFuLm5ldEJBMjM5QjQ2ODFGMUVGOTUxOEU2QkQ0NjQ0 N0VDQTAzAAoJEKipC46tDG5puYsD/RjtmsGTj/6/qSiX2u4u0QBKYA536SOSBhpp 800sD3j71cmxWHQN0JF01NdwsJRk2NHnOD/nvwB5vPSwemMg9uuF43IinKvwIr1o rYdEKpS1ytW/SmuyFkz7uV8hFH/XJugNSRnqfx/TGHmORTv387aQIzXX3nETsPtb /D4Ha/I9iQF8BAEBCgBmBQJUe+GaXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRp b25zLm9wZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRCM0FFN0VDQTlBOEM4QjMwMjZB NUEwRjU2QjdDNzRDRUIzMUYyNUYwAAoJEGt8dM6zHyXwmt8H/iV9MEXIHHUyXDNk uxIv6Q2GBOVPHLNF3JAumuDFkcdFnjuM3vUMa9nHCb0Pr+pYNaUKbJWXwlO1nqHI SA0ehkEjYhdzDFHID4YRmO+Di4gMELY5UR2FJzof6GVn3BFtEUp924HgSo7cYNGG ZpAvBsYWzN5kD36NV0OKDjRYkr4FWEsgmXrJEuWjooUECBqECbz3un32MdjmGCHs NdcL/huThZbjCbgoF4XF3WxS6FntIgVNDdszHV9NQXsQrZRN3R48u6k+i8nhPpl0 fV643aa6Bk8DpUUXxA5U1Zi/Njg7NaZQxhD/N4ljRomVgAfHQj2Oj1uG9gGyChr4 2/z3Lkk= =l43K -----END PGP SIGNATURE----- _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
