@mwilliams I was using non-twostep rule processor earlier, but switched to two step rule processor as described in the 3rd post. Two step rule processor also doesn't work for me, intra-domain mail move rules not being executed.
Current system config:
mail:~ # grep lda /etc/gromox/exmdb_local.cfg
lda_twostep_ruleproc=1
lda_mrautoproc=yes
mail:~ # rpm -qa | grep gromox
