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