sa_username_maps and bayes training

[Thomas Mueller via amavis-users]

Hi

I'm planning the Debian Squeeze to Wheezy upgrade. Just read that nice 
new sa_username_maps config option. 

If the amavisd-new is running on a central gateway. How do you train the 
bayes database ? 

IMHO calling sa-learn would need the --username option and with 
"spamassassin -r/k" I don't know of such an option. 

Or is there a amavisd-new learn command which respects the 
sa_username_maps?
