may I nag you again with this idea of self healing the file names / size of zlib compressed maildir files for version >= 2.2.11?
That's quite a lot of work for fixing something that shouldn't really be happening in the first place. I think those problems only happen once immediately after enabling zlib plugin and for some reason having the wrong (or missing) S=sizes in maildir filenames?
As far as I can reproduce my problems, this usually happens, if you have a cluster of servers with mail_plugins=zlib enabled, forgot to enable zlib of one of the servers and enable zlib_save.
The zlib enabled servers write compressed mails to disk with correct S-Value.
If you access these compressed mails via the server without zlib plugin, this server will rename the mails to a corrupt S-value, which implies that none of the zlib enabled servers can read the mails any more nor repair them.
Yes, I know, that this a layer 8 problem, but I would sleep better when I'd know that dovecot can repair this issue for me be fixing the S-value automatically.
Running http://dovecot.org/tools/maildir-size-fix.pl for all users once should fix that. So I don't really see this worth spending time on.
This may work on a private site, but not on a big cluster. There a missing zlib plugin will faster break your mailboxes than your script can find the broken boxes...
Tschoeeee
