dovecot - Jan 2012 - Dovecot LDA and address extensions - folders flood

Hi list,

This post is slightly OT, I hope no one will take offense.
I was following the wiki on using dovecot LDA with postfix and implemented,
for our future mail server, the address extensions mechanism: an email sent
to "validUser+foldername at mydomain.com" will have dovecot-lda
automagically
create and subscribe the "foldername" folder. With some basic
scripting I
was able to create hundreds of folders in a few seconds. So my question is
how do you implement this great feature in a secure way so that funny
random people out there cant flood your mailbox with gigatons of folder.

Thanks,
kfx

Don't have it autocreate the folder...

Seriously, there is no way to provide that functionality and have the 
system determine when it is *you* doing it or someone else...

But I think it is a non problem... how often do you receive 
plus-addressed spam??
