I am facing the same problem when i try to send bigger files from my Gmail account to the above email account as well.

I need my client to send and receive files greater then 10MB. Please help me to solve this problem. Thank you in advance.


I manage to solve the problem by include

message_size_limit = 51200000

at the end /etc/postfix/

and restart the postfix server

/etc/init.d/postfix reload

51200000 = 50MB

now the email server can receive email size not greater than 50MB. hope this could help!
