The SMTP-based content filter server announces a SIZE limit of 33554432.
If that is not the limit that you need. change the content filter.
Assuming this is the setup:
upstream Postfix SMTP client -> content filter -> donwstream Postfix SMTP serer
You can test this by hand with
telnet localhost port-of-content-filter
ehlo localhost
The filter will announce SIZE=33554432
Some content filters will announce the SIZE limit from the down-stream
Postfix SMTP server. In that case, you need to change the settings
there.
You can test this by hand with
telnet localhost port-of-downstream-smtp-server
ehlo localhost
And verify that this announces the SIZE= value that
you expect Postfix to use.
