cannot receive email more than 6 MB

Hello All,

running firmware 5.2.13 , we are facing issue , cannot receive  email if the size greater than 6 MB

in my mail server i changed "message receive Size=30MB". we want to allow users to receive message until 10 MB.

what should to do to achieve this task.

SMTP configuration:

config smtp

set ports 25 set status enable set inspect-all disable set options fragmail oversize splice set oversize-limit 10 set uncompressed-oversize-limit 10 set uncompressed-nest-limit 12 set scan-bzip2 disable set server-busy disable
