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

Great, more help desk idiots! There are no Thunderbird servers. Thunderbird is software that runs on YOUR computer and connects to your email providers server. The message would be from THEIR server.
