I am using Commons Net 3.11.1.

I am contacting a Microsoft Email server via IMAP. Sometimes, its 
initial reply is unexpectedly long, and the IMAPReply class barfs:

org.apache.commons.net.MalformedServerReplyException: Received 
unexpected IMAP protocol response from server: '* OK The Microsoft 
Exchange IMAP4 service is ready. (BACKENDAUTHENTICATE) 
[TQBXADQAUABSADAANABDAEEAMAAyADMAOAAuAG4AYQBtAHAAcgBkADAANAAuAHAAcgBvAGQALgBvAHUAdABsAG8AbwBrAC4AYwBvAG0A]'.

org.apache.commons.net.imap.IMAPReply.getReplyCode(IMAPReply.java:119)
     at 
org.apache.commons.net.imap.IMAPReply.getUntaggedReplyCode(IMAPReply.java:130)
     at org.apache.commons.net.imap.IMAP.getReply(IMAP.java:288)
     at org.apache.commons.net.imap.IMAP._connectAction_(IMAP.java:152)

I have brought this up before. Perhaps this time it might get at least 
an ack? Thanks.
