it works anyway as designed

remove wiki, and ebuilds or even crash the source does not prevent 
running servers to continue using it

one more thing i like to say is that i self stay on 1.x to prevent 
migrations problems if there is changes in maildir user setup, i just 
say if, it póssilbe 10 mins work to upgrade to 2.x on gentoo, but there 
will not be a way back then

here i have dovecot ebuild in my own overlay, atleast so i can rebuild 
from source again if needed

what ever AIUI means

to the OP question, no content cant be changed, it would either be an 
accept mail or reject it, but if you use sieve then you can configure 
reject msgs untested this since i use dovecot-lda, and then postfix 
would bounce to innocent senders, yark
