Is it possible to use Linq to replace this Foreach loop

Is it possible to replace the foreach statement with a Linq command? 

            string recipient = "recipients could not be defined"; 
            if (mail.To != null && mail.To.Count > 0) {
                var addresses = mail.To.Select(r => r.Address);
                foreach (string s in addresses) {
                    recipient += s + " ";
                }
            }

If I had ReSharper then I'm sure it would have come up with an appropriate suggestion but I don't. This question uses Concat and that feels like it should help but I'm not certain as to what object to use in the Concat.

Rather than using the Linq foreach (which is only available on List<T> unless you've written your own), you can do it backwards and avoid the string concatenation in the process:

recipient = string.Join(" ", mail.To.Select(r => r.Address));

This replaces your var addresses... onwards.
