You can write a shell script that is executed from your MTA instead of 
the Dovecot LDA. Perform the process-mail task from within that script 
and then call the Dovecot LDA from the shell script (and pipe the 
message to it).

Yes, you can pipe the message to the Dovecot LDA from procmail. This 
would be similar to the solution described above, only using Procmail 
instead of a shell script.
