http_proxy understands the format <username>:<password>@<my proxy>:<proxy port> so in this case the @ is probably being interpreted as server identifier. I would try enclosing the user name in single quotes or adding a \ before the @. If these do not work your only option may be to contact the proxy admin and obtain a username without the @
If putting '@' to escape the at sign didn't work, have you tried using the URL escape code of '%40' to represent it?
