Problem using imapsync 1.359 - never attempts login to host2

[Clint Dilks <clintd at scms dot waikato dot ac dot nz>]

Hi,

I work for a New Zealand University that is wanting to use imapsync to 
assist with migrating to GoogleMail.  I have used older versions of 
imapsync in the past and definitely though this would be possible.  But 
upon testing this I found that imapsync hangs never attempting to 
connect to host2.  So to define the problem further I then tried using 
imapsync to sync mail from one mailbox on our current mail server to 
another mailbox on our existing mail server.  I still see the same 
behavior.  Whichever mailbox I define as Host1 gets logged into but 
host2 is never contacted.

Any suggestions as to what I am doing wrong?  The machine running the 
sync is a 64 Bit CentOS 5.5 install

/usr/bin/imapsync --debug --debugimap --authmech1 PLAIN --debug --host1 
<MAILHOST> --user1 <USER1> --password1  PWCHANGED --tls2 --ssl1 --port1 993 
--authmech2 PLAIN --host2 <MAILHOST> --user2 <USER2> --password2  PWCHANGED 
--tls2 --ssl1 --port2 993
