[plug] Attachment size in postfix

[alben b. alteza]

Does anyone there know where to assign attachment size in postfix?   I did not assign any attachment size restriction in my postfix "kasi di ko alam kung saan" but when I email with a 40M attachment it returned mail stating exceed max size allowed or similar.   I would like to know where can I make postfix accept larger attachment size.   thanks in advance!   alben
