I had a same problem but i am using zimbra firstly i did in zimbra sudo
su - zimbra #(or just su - zimbra)
zmlocalconfig -e imap_max_request_size=102400000
zmprov mcf zimbraMtaMaxMessageSize 102400000
zmmailboxdctl restart
and then i changed main.cf of postfix like you , but opposite host of
user domain postfix did not accept mail because of 10mb limit.
Conclusion
be sure which postfix returned this error to you (your server, or from
other side) and be sure your mail program (thunderbird, evolution etc.)
has not limit of 10 mb
and also you must add uploaded file size settings in main.cf (if you
attach a file)
and be sure service has been restarted
