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

That's the only reason I can think of for this. dirsize backend really sucks with maildir. -------------- next part -------------- A non-text attachment was scrubbed...
