I should warn you that there are subtle changes to dovecot config
between 2.0 and 2.2 that may give you issues when switching.  You will
likely have to tweak a few config options to get it to work the way you
want.

If you're using MailDir storage then you can simply move the messages
yourself, it's as easy as using the mv command to move them from one
directory to another and you won't need the doveadm move command.

If you have any more questions feel free to ask them here or in
#ghettoforge on FreeNode IRC.

Peter,
thank you, I was guessing this is what might be needed, and I appreciate the
heads up on what to expect when I do the update.

The resolution I achieved is a bit more convoluted, but it consists of the
following, and remains consistent with centos 6.6 version of dovecot:

wrote a cron script that does the following:

stop fetchmail process
stop sendmail process
stop spamassassin process
run sa-learn against the user's spam_to_learn mailbox
run 'doveadm mailbox unsubscribe' to unsubscribe the spam_to_learn
mailbox
run 'doveadm mailbox rename' to rename the spam_to_learn mailbox to
${date}_spam_learned
run 'doveadm mailbox subscribe' to subscribe the ${date}_spam_learned
mailbox
(for testing and validation purposes, I will disable this eventually)
run 'doveadm mailbox create' to create a new spam_to_learn mailbox
run 'doveadm mailbox subscribe' to subscribe the new spam_to_learn
mailbox
then
run sa-learn against the user's ham_to_learn mailbox
run 'doveadm mailbox unsubscribe' to unsubscribe the ham_to_learn
mailbox
run 'doveadm mailbox rename' to rename the ham_to_learn mailbox to
${date}_ham_learned
run 'doveadm mailbox subscribe' to subscribe the ${date}_ham_learned
mailbox
(for testing and validation purposes, I will disable this eventually)
run 'doveadm mailbox create' to create a new ham_to_learn mailbox
run 'doveadm mailbox subscribe' to subscribe the new ham_to_learn
mailbox
start spamassassin
start sendmail
start fetchmail

Note that the doveadm-mailbox help indicates that some of these steps can be
combined by using the -s option to subscribe or unsubscribe, depending on the
function invoked (rename, create, delete), but they don't work. You need to
do
the steps manually, one at a time as I have them listed here.

When I have more time, I will go ahead with a dovecot 2.2x install and report on
any issues I find.

thanks,
-chuck

You're welcome and while I'm flattered that you would consider my build
of dovecot I do tend to recommend that people only use it if they have a
real need for features that are not in 2.0 so I'm not disappointed that
you decided to stay with the CentOS version for now.  I don't pretend to
be as reliable in keeping my packages up to date as RedHat (and hence
CentOS) is, either as I have to do it in my spare time of which I do not
have a lot.  That said if you want to experiment and eventually move to
2.2 I'm happy that you want to use my package for it.

Good luck and I'm happy to help if you have further need.
