ReiserFS does not commit link() synchronously (mounting with "sync"
doesn't change anything). Therefore, if there is a power outage during
the Maildir delivery or if qmail-smtpd answered the final "queued"
message without actually commiting the link in queue/todo, the message
will not be processed by qmail-send.
Here is a patch to make Qmail more reliable for Linux users using a
ReiserFS partition.
