1) Make sure you're running Perl 5.8.8:

a) check perl -v to make sure it says 5.8.8

b) if you see 5.8.7 or something else, follow these steps:

1) wget http://layer1.cpanel.net/perl588installer.tar.gz
2) tar xfvz perl588installer.tar.gz
3) cd perl588installer
4) ./install
5) /usr/local/cpanel/bin/checkperlmodules

2) Upgrade YAML::Syck:
1) /scripts/realperlinstaller YAML::Syck

3) Remove any SARE/openprotect spamassassin rules

These seem to be not compatible with SpamAssassin v3.2 see This Thread for more info.


4) Upgrade from mbox to maildir.

This can be done by running /scripts/convert2maildir.

WARNING: Make sure to run the option to back up your mail first.

When running the conversion, you should watch out for the following:

**IT WILL TAKE A LONG TIME. Don't kill the process or you'll be left with a lot of half-converted mailboxes and angry clients who aren't getting mail.

**Mail will not be delivered during the conversion, it will be instead queued until the conversion is complete and then delivered.

**Make sure your mailbox permissions are ok before converting and make sure your clients aren't currently using mailboxes called /cur /new or /tmp
