Hi,
We’re using dovecot 1.0.7, which seems to be the latest version available on CentOS 5.
Downloading emails are dead slow. Really small emails goes quickly, but normal emails and emails with attachments are so slow to download it’s almost ridiculous. I’ve googled some and found that it could be related to quota, but I disabled the quota plugins on imap with no difference.
