problems with imapsync from cyus

[g8se]

I'm running imapsync like the following:

imapsync --debug --dry --ssl1 --nosyncacls --subscribe --syncinternaldates --noauthmd5 --host1 dmz01.mel.strategicdata.com.au --user1 ghc --passfile1 /tmp/wHyYkRpRcm --sep1 . --prefix1 INBOX --folderrec INBOX --host2 zimbra.mel.strategicdata.com.au --user2 ghc --passfile2 /tmp/wHyYkRpRcm

I'm using ldap auth on both host1 and host2, so can use the same passfile. Host1 is a cyrus 2.1.18 imap server, from the Debian Sarge package. Host2 is Zimbra opensource edition, 4.0.5, running on Debian as well.

I've tried following the details at http://wiki.zimbra.com/index.php?tit...nded_Method.29, but I'm still having problems. It looks like imapsync doesn't think the zimbra inbox exists, so it happily syncs emails from the Trash folder over, but nothing in the inbox.

Can anyone help?

The problem is that your cyrus implementation uses the oddball standard cyrus namespacing, where all folders -- even the "top-level" ones -- appear under INBOX. Your invocation of imapsync maps "INBOX.Trash" to "Trash" correctly, but it also maps "INBOX" to "", and there's no "" folder under zimbra (or any other IMAP server).

According to this forum post, you should be able to reconfigure your cyrus server with the "altnamespace" config option, which puts top-level folders on the same level as INBOX rather than as its subordinates. I think you should then be able to run imapsync successfully, though you may have to remove the --prefix and --folderrec options to make it work.

Thanks for the response dkarp. As a work around I've decided to invoke imapsync twice. Once to do the recusive copy of all folders except INBOX (which is what I had working already), and once to copy the INBOX itself.

I'm already wrapping imapsync up in a script, so this isn't really an extra annoyance.

Cheers

When you're done, can you post your script to the migration wiki? I'm sure that you're not the only one dealing with a Cyrus migration...
