Why does email I send to any of the lists get returned to me because postmaster@outlook.com doesn't like my email domain? [quote] Delivery has failed to these recipients or groups: amdlnx60@googlemail.com<mailto:amdlnx60@googlemail.com> Your message wasn't delivered because the recipient's email provider rejected it.

They should be told about what is happening, no? Do I need to filter everything from @outlook.com to the trash? Are @outlook.com addresses real, or just anti-spam admin addresses? NAICT, reporting this to abuse@earthlink.net hasn't cut these down any. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg.
