when i send mail from Thunderbird i get error message "An error occurred while sending mail. The mail server responded: 5.7.6 Message rejected as spam (CM).. Please check the message and try again." i don't get it all the time and have narrowed it down to the ebay email id in their emails i reply to i use optusnet as my mail server,if i send from their web mail it doesn't get rejected. optus support tell me that the email has to go through a thunderbird email server before they get it and that is where it is being rejected ????? any help would be appreciated
