I have a question in regards to mailman's recovery abilities. Let's say mailman is running and sending out messages to a large list and the machine crashes or is rebooted, does mailman pickup where it stopped? Or is the run gone forever?
I've had way too much experience with this lately... :(
Mailman soldiers on just fine. The problems we've run into are with some of mailman's files getting corrupted because they weren't synced to disk when the machine crashed -- the standard problem with any crash. I've had to rebuild a couple of list config databases, and toss out a few corrupted pending pickles. We plan to try the synchronous-write option, do backups (!), and maybe even replace the flakey hardware that's been causing the crashes.
Doesn't the new SYNC_AFTER_WRITE flag address this issue? Here is the doc for it:
# This flag causes Mailman to fsync() its data files after writing and # flushing its contents. While this ensures the data is written to disk, # avoiding data loss, it may be a performance killer. Note that this flag # affects both message pickles and MailList config.pck files.
