[SOLVED] IMAPSYNC Issues with Initial SSL Connection

[the_griz]

I am having trouble setting up for a migration from a standard IMAP server to ZIMBRA.

I have imapsync fully installed.

I ran this command:
imapsync --buffersize 8192000 --nosyncacls --subscribe --syncinternaldates --host1 <myIMAPserver> --user1 <account1> --password1 <password1> --ssl1 --host2 <myZIMBRAserver>--user2 <account2> --password2 <password2> --ssl2

The results were:
$RCSfile: imapsync,v $ $Revision: 1.255 $ $Date: 2008/06/24 16:38:49 $
Here is a [linux] system (Linux <myZIMBRAserver> 2.6.18-92.1.13.el5 #1 SMP Thu Sep 4 03:51:21 EDT 2008 x86_64)
with perl 5.8.8 and the module Mail::IMAPClient version used here is 2.2.9
Command line used :
imapsync --buffersize 8192000 --nosyncacls --subscribe --syncinternaldates --host1 <myIMAPserver> --user1 <account1> --password1 <password1> --ssl1 --host2 <myZIMBRAserver>--user2 <account2> --password2 <password2> --ssl2

Turned ON syncinternaldates, will set the internal dates on host2 same as host1.
TimeZone :[EST]
Will try to use CRAM-MD5 authentication on host1
Will try to use CRAM-MD5 authentication on host2
From imap server <myIMAPserver> port [993] user [<account1>]
To imap server [<myZIMBRAserver>] port [993] user [<account2>]
Error connecting to <myIMAPserver>:993:

I have tried
openssl s_client -connect <myIMAPserver>:993
and it works/connects fine.

Any ideas?
Thanks!

Here is my *NEW* approach to this:
- Despite several attempts I could not get imapsync to authenticate an SSL encrypted channel. Imapsync requires a specific OLDER version of the Perl Module IMAPClient and maybe my SSLv3 connection could not be understood by it..? (anyone agree?)
- I was able to get a non-SSL login to work. By locking down the imap ports to just between the exisitng mail server and the zimbra server, I felt comfortable thta the machine was not overly exposed. The command that worked was:

imapsync --buffersize 8192000 --nosyncacls --subscribe --syncinternaldates --host1 <oldmailserver> --user1 <olduseracct> --password1 <olduserpassword> --authmech1 LOGIN --host2 <zimbraserver> --user2 <newuseracct> --password2 <newuserpassword> --authmech2 LOGIN


The transfer is SLOW but reliable!
