I'm hoping to take advantage of authentication caching via dovecot-auth. I see that posfix can communicate with Dovecot-Auth, via SASL, but from what I can see, postfix only does this for authentication checks. Not 100% sure how postfix handles virtual_transport (I assume it needs to do a lookup via virtual_mailbox_maps), but I can't see anyway to get virtual_mailbox_maps to use dovecot-auth ether. I guess I may just have to get the virtual_mailbox_maps to look up userdata via SQL as well as Dovecot, but I was hoping to avoid what will be 3 similar lookups one after the other (dovecot-lda is in use as well).
My intended setup is "Postfix" -- LMTP --> "Dspam" -- DeliveryAgent --> "Dovecot-LDA", with each stage currently doing a SQL lookup for user information. It would be awesome if they all used SASl via Dovecot-Auth so that the Auth cache does it's job! Reading the doc files in Dspam is confusing me, as the relay file seems to be mixed up.
Any help greatly appreciated!
