Ah I did not read your original email closely enough and didn't realize 
that.

The error in your original message seems to indicate you are running into 
the mysql limit rather than postfix (which might still limit but that would 
happen later) or sympa.

I don't know how sympa stores the message in the database but maybe there 
is some additional metadata/headers that are inflating it?  Maybe David or 
others can comment...

What happens if you set the mysql max_allowed_packet to something much 
larger like 32mb? Also did you try the test listed at
