Since I subscribe to some heavy traffic lists like Fedora, Ubuntu and LKML I sure do (this is a RHEL4 x86_64, dual Opteron, 6gb ram , hardware RAID5, ext3 based Maildirs). I've gotten up to 50k messages before without issue except that I had to disable FAM support. It seems FAM and/or Gamin in conjunction with dnotify will max out around 5k messages. It dies very badly too, it starts chewing up 100% of the CPU and does nothing until I reset imapd. Never fear though, Gamin using inotify (the newer 2.6.18+ kernel driver for file change notification) went considerably higher, 10,000 messages or so and more importantly, it didn't kill my server when it failed, it simply failed to report IDLE status on folders larger than that which isn't that big of a deal anyway. I'm waiting for RedHat Enterprise Linux 5 which has inotify support in the kernel, till then I've disabled IMAP enhanced IDLE. All this to say this is the only scaling issue I've run into with Courier, it's not really Courier's "fault" and the article on Courier not scaling well is pure rubbish. You can tell based on the fact that the author attributes his statement to his testing alone. Jay -- Jay Lee Network / Systems Administrator Information Technology Dept.
