[Dovecot] lstats on all files in Maildir when opening an e-mail.

[Tan Shao Yi]

Hi,

I'm running RC19 on a Solaris 10 SPARC box.

It seems that whenever I open an e-mail in any folder via IMAP, dovecot 
appears to scan every other folder in the Maildir.

A truss reveals that it is lstat-ing every e-mail in every directory.

I'm sorry I am sending only a fragment of the truss, it's really too 
long... but is this behaviour expected?

Cheers,
Tan Shao Yi
