------------------------------------

             Summary: IMAPClient over proxy doesn't properly resolve DNS
                 Key: NET-650
                 URL: https://issues.apache.org/jira/browse/NET-650
             Project: Commons Net
          Issue Type: Bug
          Components: IMAP
    Affects Versions: 3.6
            Reporter: Matthew McGillis
         Attachments: imapproxy.java

IMAPClient when configured to use a socks proxy is not able to resolve DNS names through the proxy.


See attached sample code, if I use it with:

{noformat}
$ java -DsocksProxyHost=localhost -DsocksProxyPort=16003 -cp .:./commons-net-3.6.jar imapproxy imap.server.test.com user1 userpass
connect error: java.net.UnknownHostException: imap.server.test.com: unknown error
{noformat}

vs if I use it with the appropriate IP:

{noformat}
$ java -DsocksProxyHost=localhost -DsocksProxyPort=16003 -cp .:./commons-net-3.6.jar imapproxy 10.250.3.127 user1 userpass
* OK IMAP4rev1 proxy server ready
