Thank you, Marcus and Timothy, for your replies!

run them in your MTA before pushing stuff into the LDA? e.g. i deliver incoming via lmtp to dspam. dspam reinjects the mail into postfix. and postfix calls dovecot-lda to deliver the mail.
Then it's not per-user, or at least I could not figure out how to do this properly with postfix.

I have to agree. This isn't a LDA function. Content filters are a MTA function.
Okay, all the better, then I don't have to write the plugin. :)
You should be able to pipe all the filters together, so in your call to dovecot-lda in your mta, it just changes into one big pipe... For example
dspam --stdout| dovecot-lda -d $uorspamassasin | custom filter| dovecot-lda
I read somewhere on the net that this is pretty flakey and will fail badly in the case of intermittent errors, but I cannot find the reference anymore. Is anyone using this with success?
Also, the above spawns an expensive shell process, doesn't it?
