After years of normal operation, my Comcast email suddenly stopped working - neither I nor my wife, on our respective computers, could send or receive email via OE. After a number of tech support sessions, Comcast performed some (unspecified) fix and we were again able to send and receive, except for one remaining issue: Neither I nor my wife, on our respective computers, are able to send email to ourselves. We get the error message:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'email@example.com.'. Subject 'test', Account: 'mail.comcast.net', Server: 'smtp.comcast.net', Protocol: SMTP, Server Response: '550 5.5.0 <firstname.lastname@example.org.> domain missing or malformed', Port: 587, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
Comcast has been unhelpful on this. Any suggestions would be appreciated.
