[imp] monthly problem with deletion and moving Mails

[V Kloubert]

dear list,

i am having problems with horde evrey time when a month is changing. i  
do not know weather this has something to do with the month or with  
the fact, that the inbox on horde imp is getting full. when i try to  
move mails into another folder horde does it, but a few minutes later  
evreything is as it was.
there seems to be a problem with imap i think. can somebody give me a  
hand? is there any german consulting who likes to help?
