Removing the expires plugin, due to removing its dict, causes everything 
to work normally. for some reason, dovecot 1.2.13 with managesieve 
0.11.11 doesn't like using any dictionaries such as:

#dict {
   # NOTE: dict process currently runs as root, so this file will be 
owned as root.
#expire = mysql:/etc/dovecot/dict-expire.conf
#quotadict = mysql:/etc/dovecot/dict-quota.conf
#}


Since I use maildir, I don't need a quota dict, which means I can just 
work around this problem. I don't HAVE to use expires as I have put a 
cronjob to go around the spam and trash boxes, deleting messages over 60 
days old, for spam, and 15 days for trash.

Please, someone, explain why the dictionaries do not want to work. I 
used the sql config for both from the dovecot.org, those configs 
relating to dovecot 1.2. I thought there may be a workaround of not 
using the proxy::, as the mysql is on the same machine as dovecot and 
multiple connections would not be a problem.
