abdulkarim - you can use strfind or regexp. If the former you could do something like
eAddr = 'baashe@hotmail.com';
idx = strfind(eAddr,'@');
if ~isempty(idx)
domain = eAddr(idx+1:end);
end

Use strfind(). Be sure to make your code robust enough to handle missing @ symbols, and check if @ is in there with isempty.
email = 'baashe@hotmail.com'
atIndex = strfind(email, '@');
if ~isempty(atIndex)
% It's a valid address. Extract the domain.
domain = email(atIndex+1:end);
message = sprintf('The domain is %s', domain);
uiwait(helpdlg(message));
else
% Not a proper email address.
warningMessage = sprintf('%s is not a proper email address', email);
uiwait(warndlg(warningMessage));
end
