IMAP/LMTP/Quota locking problem

Hi,

thanks for the info. The patch was definitely added *after* 2.2.1 ... hmm, 
now that I think about it: seems like it was even added after 2.2.3! Is bug 
1270 really fixed in CVS only?

We don't get those. I wonder if we actually have separate problems. Or 
maybe not. However, in our case the sendmail processes get stuck as well, 
maybe due to our setting of DeliveryMode to interactive!?

What does "regularly" mean? We've been running the server in prdouction 
since March, 1, but it happened for the first time a little more than a 
week ago ...
