And those of us with better than a TB of mail for more than 100K accounts serviced by a rack worth of load balanced servers and a HA NFS infrastructure would be SOL.
True Maildir without all the indexing addins (like Cyrus started with) is NFS safe and scales. You take a hit up front, but you gain it back in the ability to have dozens of servers, where any server can handle any mailbox, including multiple servers accessing the box at the same time. (As it happens the IMAP client I am using now has 5 sessions up, each to a separate server the the LB and all accessing the same account.) We run courier *because* it uses true Maildir without any index based acceleration. That being said, I am working with thunderbird, in an account with 3 - 5 thousand messages per folder across a few dozen folders does well. The testbed install in a generic single CPU Opteron at 2Ghz, 1G RAM and a single 300G SATA drive. Last time I was getting complaints I spent most of a day pushing messages around with 35,000 messages per folder without issue. (Turns out the complaints were about an account with 230,000 messages in the inbox). Simon wrote: > On 5/13/2008, Sam Stern ([EMAIL PROTECTED]) wrote: >> I've had this problem as well.
