rlm stands for 'robust lm'. What you need here is 'robust glm'.
I've already replied to a similar message by you,
mentioning the (relatively) new package "robustbase".
After installing it, you can
use
robustbase::glmrob()
[or just glmrob(), after attaching the package by "library(robustbase)"]
and its summary function does provide you with robust standard
errors (and even P-values which you seem to like particularly ;-).
