Hi all,

I'm running dovecot version 2.0.19 (Ubuntu 12.04) and I discovered some unexpected behaviour related to the Dovecot managesieve module. When connecting to the managesieve service from a client for the first time (e.g. roundcube webmail), I get an application error. This is logged by Dovecot:

Error: sieve-storage: opendir(/var/.../exampledomain/exampleuser@exampledomain//sieve) failed: No such file or directory.

At first glance I thought the problem was caused by the "//" in the directory path. I assume this is just a concatenation of the user virtual home directory (in my case "/var/.../exampledomain/exampleuser@exampledomain/" and the default sieve folder (~/sieve). While this looks wrong it seems not to be the actual problem (should be fixed though?)

Then I noticed that the user home directory and sieve data were actually properly created despite the error. When connecting again, it worked without error. The problem can be reproduced by deleting the users virtual home directory and connecting again.

A guess would be that the automatic creation of the virtual users homedir folder structure is some asychronous process not being completed in time.

I also found this older thread with a similar issue: http://osdir.com/ml/dovecot-development/2010-05/msg00018.html

Could also be worth mentioning that I'm running Dovecot on a virtualized host with possibly relatively poor I/O performance (maybe faster environments don't have this problem).

Thanks for looking into this, and thx for the really neat dovecot software package!

Cheers, L.
