[Dovecot] Confusion of Sieve filter scripts and the file separator. (Amatuer Siever)

Hello,

I have just been playing around with sieve filters to split up all my incoming mail into the correct directories. I have created some subdirectories to put mailing list emails in and just want to check if my thinking is correct. I am using namespaces with the '/' character as the separator. When creating the fileinto line on my sieve scripts I thought I would have to use the '/' character to separate the folders (as horde mail also does), but that doesn't work (and produces a "Invalid folder" error) instead I must use the '.' character. I am using the dovecot deliver module and managesieve for my sieve stuff (dovecot 1.0.13). I am just wondering if this is the correct behaviour or if it is a bug of sorts.

Cheers.

From, Jack
