SASL auth cache?

[Tom Sommer]

Hi all

I just observed Postfix not picking up changes in the SASL auth backend, 
is there some kind of cache involved here? I had to restart postfix in 
order for it to see that a (spamming) SASL account no-longer existed, 
even though the Dovecot auth-backend was aware of this.

Thanks.
