Then it sounds like your imapd was not compiled with --enable-fulldirhash. The argument to rehash should match however your imapd was compiled (and using someone else's package may make it hard to tell).Yeah, you're probably right; I just saw a directory full of capital letters and assumed it was all of them. I do recall prime-based hash functions being better. However, after I did the hash, imapd seemed to still be using the traditional first-letter-hash. I had this in my logs and couldn't open my mailboxes:
Jun 8 17:51:46 rheingold imapd[14729]: IOERROR: opening /home/imap/w/user/wcooley/cyrus.header: No such file or directory
Our customers have a 10MB mail quota which they can fill up prettyYour call, but even when I worked at an ISP we had far more problems with customers who used POP than those that didn't.
quickly. We don't want them leaving their stuff on our server, and they
want to be able to have their mail even when they're off-line (I know
there's IMAP sync, but it's questionable how well supported it is, and I
don't really want to try to explain it to customers).
Also, reducing the Cyrus timeout isn't going to help clear the half-connected sockets in the kernel if the customers just disconnect without dropping all their TCP connections first.
