Me too. Check the size of the message, if its bigger than the value in the ESF variables.conf (or variables.conf.custom), then adjust the value.
This ESF value goes for both, SA and rSpamd. You can see in the mail header, if the message was scanned at all. In my case it was not, because size was ~1,5mb and max size in ESF was 1024k, so I changed that to 2mb.
And if you make a new variables.conf.custom, dont forget to use "==" instead of "=" (I got this wrong at first attempt, Zeiter corrected me, thanks to him!)
