Redhat 9 ships with UW IMAP, with the most compatible mailbox format. This doesn’t scale well, for several users, or for one user with a lot of mail (that’d be me). From what I’ve read, there is no email indexing, and only one process can lock the mail file at a time. In squirrelmail, it’s currently taking minutes to load each page of email, and I’m going nuts (hah).
So I’m going to install Cyrus IMAP, which is supposedly “hard to configure”. Dang it… to be continued…
