Why are my emails addressed to yahoo and mindspring clients being rejected for syntax errors?

Here is the error message:

Delivery to the following recipient failed permanently: 

    Lisa@xxxxxxx101@yahoo.com

Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain yahoo.com by mta7.am0.yahoodns.net. [98.138.112.37].

The error that the other server returned was: 501 Syntax error in parameters or arguments

Having two '@' characters looks rather problematic.

Which version of Thunderbird are you using? I read another posting today where there were stray characters apparently being appended to the email address.

Can you identify which parts of the address being used are correct, and which bits appear to have been added?

Thanks, Zenos! My little test seemed to go through with no problems. One additional piece of information that puzzles me is that I used the address with the superfluous @ for two weeks before the failures - hmmmm.

Having said that, I should not have used the @ in the address - period. It would be nice to have Thunderbird catch that when I entered the address initially. I am currently using Version 32.0, which I believe to be the latest version.

Thanks for solving it so quickly!
