There are no directories below ~/mail So you mean that Personal, School and Trash are files? That would indicate than they are standard mbox files. Maildir format doesn't work that way. With maildir each mailbox *is* a folder, with three standard subfolders: new (for new message), cur (for old messages), tmp (I don't know what this is for, probably temporary storage of some kind). And each message goes in a seperate file and they all have weird names so that they are guaranteed to be unique, I think they use a timestamp, the inode number, and the hostname or something like that. Maildir has certain technical advantages, and certain not so technical advantages. For example there is no need for locking, no rewriting of entire mailbox, all this boosts performance and reduces risk of corruption even in the event of a bad crash. The performance advantages made me switch from uw-imapd to courier-imap at work. People were getting huge attachments that crippled uw-imapd. I think once I saw someone get a single email with 37 megs of attachments. Bijan -- Bijan Soleymani <bijan@psq.com> http://www.crasseux.com
