Can't send email all of a sudden - complains about domain - mail server responded: 5.1.0 sender rejected. CXSNDR

 ... use Thunderbird - no changes to my account or TBird settings.

Can send from webmail and gmail to hav@hav.com but reply fails with the error.

Had support send me mail to my cox addr directly, WAS able to reply to that one (which means I was replying From: hav@hav.com)

  • ok - problem seemed to resolve itself ... working again now
