Well, amavisd also process all the mails so maybe more statistic could be useful to be shown directly (or maybe for getting processed later by some MRTG tools), without having to take an handy calculator (e.g. taking the total number of MsgSize and divide by the number of messages) :-) >> I also obtain strange values for this parameter.
