I did an "strace" on one of the hundreds of lmtp processes.

It's doing stat() on all files in the new folder for the receiver:

stat("/var/mail/dovecot/xxxx/xxxx/new/xx.xxx.xxxx.xxxx.com", 
{st_mode=S_IFREG|0600, st_size=15505, ...}) = 0

etc.

The "new" folder contains hundreds of thousands of files.

Is there any way to prevent all these stat() calls? It seems like 
something there would be an index or cache for?

Thanks
