BT Yahoo Mail - Forum Thread
My ISP is BT.We access our emails using Windows Mail Popped from BT Yahoo Mail. We have 4 email addresses. We have no problems sending or receiving emailsI have recently encountered problems forwarding and replying to emails sent to me. They just seem to hang in the out box and a standard error message pops up, see below.I have checked BT Yahoo Mail using Web Mail and cannot see why there is a problem un less there is some obscure setting I have not found.An unknown error has occurred. Subject 'Fw: Mr **********, your November newsletter from ***', Account: 'mail.btinternet.com (2)', Server: 'mail.btinternet.com', Protocol: SMTP, Server Response: '451 Invalid Smtp line - Should end with CRLF', Port: 25, Secure(SSL): No, Server Error: 451,
Error Number: 0x800CCC6A
Can't really help with your question but the Vista forum seems to get litle response... I would ask again in the "Helproom"
I have now found out what the problem is.I have
used AVG free for more than 12 years with no problems what so everand found it to be excellentI recently received a pop up suggesting I download and install the latestversion AVG 2011, which I did.Since that date I have been having problems forwarding and replying to emailusing BT Yahoo Mail via Windows Mail.After much head scratching I came to the conclusion the problem could be resolved by removing the tick in Advanced Settings to "CheckOutgoing Mail" would solve the problem. Which I am pleased to say it did. In the past I have always used the default settings in AVG.I feel this must be a conflict with BT Yahoo Mail. At the time prior topreventing the scanning of outgoing emails I was able to access another ISPand forward emails OK from this PC using identical settings in AVG.
I would be interested in any comments.
