What's new

I decided to rewrite Jarosław's script to fix a few bugs I stumbled upon while migrating my bare-Postfix server to Zimbra, namely:

  • all folders were merged into the main folder due to a bug in the script (hint: '=' instead of '==').
  • folders with spaces in their name were not imported and caused an error
  • import messages from accounts across multiple domains, if needed
  • made the code readable
  • no need for two loops


How to use

The script expects to find the mailboxes in the current path! The structure of maildirs must be as follows:

domain/username/{cur|new|tmp}
domain/username/subfolder1/{cur|new|tmp}
domain/username/subfolder2/{cur|new|tmp}
...

After the script has run, every zimbra user will have a subfolder in his mailbox called 'old-mbox' (feel free to change the name at the beginning of the script). The hierarchy of subfolders is maintained under old-mbox.

The code

#!/bin/bash

# Postfix virtual transport -> Zimbra mailbox migration
# written by NERvOus (http://www.nervous.it) - 2009-12-25
# minor fixes by NERvOus (http://www.nervous.it) - 2013-07-23

# base folder where msgs will be imported
BFOLDER="old-mbox"
ZMMBOX="/opt/zimbra/bin/zmmailbox"
BDIR=$(pwd)

echo You must run $0 from inside /var/mail/virtual directory
echo $0 expects to find the mailboxes in the current path!
echo The structure of maildirs must be as follows:
echo 
echo "domain/username/{cur|new|tmp}"
echo "domain/username/subfolder1/{cur|new|tmp}"
echo "domain/username/subfolder2/{cur|new|tmp}"
echo ...
echo 
echo All folders will be stored in a subfolder called $BFOLDER
echo The hierarchy of subfolders will be maintained under $BFOLDER.
echo 
echo Press Enter to start, CTRL+C to abort.
