Would somebody please try to enlighten me!!!!
Today, I attempted to send an e-mail, as usual with Windows Mail, on my default SMTP account, viz:- btinternet.com. The "Send" failed and produced an error message with the subject information. The crux of the text was "451 Invalid Smtp line - should end with CRLF", Port: 25, Secure (SSL): No, Server Error: 451, Error Number 0x800CCC6A.
Try as I might, I am unable to find any "useful" information. I already know what it says - I can read!!!! What I want to know is what it really means, and how to go about solving the problem of being unable to send e-mails on my default account. To my knowledge, no changes have occurred since the last time I used it and checking the account details, all appears to be in order. If I could even find out which "Smtp line" was missing the carriage return line feed command, I might be able to sort it!!
I don't know how many times I encounter silly little problems like this and always seem to come up against a host of information which proves to be of no earthly use at all!!
I'd be awfully grateful if somebody out there can help.
Many thanks, in anticipation,
Have you read may help or not
Many thanks Hamish72. This is much more like it!
My searches didn't point me in the direction required.
I suspect the solution has now been found but I'll try and post more info after I've checked.
In the meantime, many thanks
