Funny. I remember the complains with Exchange having a 2 GiB limit per mailbox, and here we go with a 50 MB default limit.
It's probably just an old default Postfix setting. My guess is it's not used much anymore - people set it to 0, and then leave the mailbox/-dir to be governed by quotas in dovecot.
And it has to load the entire mbox in RAM, to just append a new mail at the end?
I wouldn't think so, but we use maildirs.
And that's why I hate the ext[234] family of file systems. You either run out of file blocks while there's still space devoted to i-nodes or you run out of i-nodes while there's still space available. The whole idea of pre-provisioing i-nodes, the idea of devoting a fixed amount space to i-nodes and a fixed amut of space to data blocks is right out of the of the original UNIX of the 1970s. The real B-tree file systems, notably ReiserFS, XFS, BtrFS, don't have this limitation. They allocate space as needed. The irony here is that ext4 is a brilliant, otherwise superbly designed and crafted file system, really superb. Really drool-worthy in many aspects. But it has this idiotic 1970s approach to pre-provisioning, setting the fixed amounts of space at MKFS time. Yes, it's more flexible about that than its extFS predecessors, but whenever I've used it for email or enews I've been bitten by this. Maybe Richard is smart enough to work out the pre-provisioning so that doesn't happen to him. Yes, he's smarter than me about FS matters, but I really don't want to have to spend time with that sort of calculation. Its things like that make me realise that perhaps BtrFS is a good choice.
