we have the same problem

imapsync 
--host1 mail.domain.com 
--user1 username 
--authmech1 PLAIN 
--ssl1 
--host2 zimbramail.domain.com 
--user2 username 
--sep1 / 
--prefix1 / 
--sep2 / 
--prefix2 "" 
--folderrec INBOX -
-regexflag 's/NonJunk//g' 
--regexflag 's/Junk//g' 
--regexflag 's/label*//g'

But if I look at the output from imapsync, I see this:

flags from : [\Seen $label1][]
81 NO APPEND Invalid flag list

I am trying to migrate mailboxes from Open-Xchange 5 to Zimbra .
Has anyone seen this and/or know what to do??

Thanks
