sieve autocreate

[Marten Lehmann]

Hello,

does sieve include any form of autocreating a "fileinto"-folder?

I know that there's an option in Cyrus, but that doesn't help me in this 
case. Each user shall be able to define a name for a Junk-folder. 
Usually this is "Junk" (in Thunderbird), but in other Applications it 
might be called "Spam", "Unwanted" or even with Umlauts "Unerwünschte 
Nachrichten".

I surely put this name after the "fileinto" command, but is there also a 
way to create this folder automatically or check if it exists at each 
delivery?

Regards
Marten
