Wait a minute? X-UIDL? If the problem is 50/50 read/write ratio, then why
don't you just have your users use IMAP to access their mailbox?
You avoid writing X-UIDL's, you can still use Maildir (if using Cyrus, you
are writing maildir style anyway), and you read when needed.
We have about 40,000 mailboxes on a single machine, some with as many as
30,000 messages in each mailbox, and we haven't had problems yet. Then
again, most mailboxes are realitively small.
