OK
But I am getting this message when both statements are true
1) sending from an e-mail address through an SMTP server tha
does host my address an
2) I am trying to send to a valid addres
I am using Outlook 200
I have deleted and recreated my e-mail account but this error message is returned 60% of the time
Once a valid address has been rejected it stays rejected. Over a period of time the number of people I can send e-mails to is reducing
If I use IE to access my ISP mail server, I can send and receive e-mails without problems
Do I need to reinstal Outlook, or are there parameters, filters I can reset
