I'm having some problems with my migration from SLOX4.1.

A test migration went fine previously but when I came to run the Cyrus 
Import script for real, I hit...

Starting postfix:                                          [  OK  ]
Starting cyrus-imapd: preparing databases... error!        [FAILED]
Starting OX-SESSIOND:                                      [  OK  ]
Starting OX:                                               [  OK  ]
Starting OXWebmail:                                        [  OK  ]

Starting OX-XMLRPC-Daemons:                                [  OK  ]
Setting ACLs of cyrus to mailadmin
Exception in thread "main" javax.mail.MessagingException: Connection 
refused;
   nested exception is:
         java.net.ConnectException: Connection refused

         at javax.mail.Service.connect(Service.java:137)
         at OXCorrectFolderACL.main(OXCorrectFolderACL.java:54)

Any idea what this means?

All users and their folders appear after this, but the folders contain no 
messages.

And when re-running the script, should I remove any directories or do 
anything beforehand (other than something to correct the error), for 
example remove /var/lib/imap?

Many thanks in advance,

Mark
