Do you have SASL and OpenSSL linked into sendmail...?

I get sizes of 7932K / 4036K (vs 5820K / 2732K without) just from starting it 
up, and that grows considerably if you actually send mail through it using 
STARTTLS.  When idle, they seem similar, but when you put even a light load 
through them (say 10K messages per day), sendmail is much bulkier in practice, 
IMO.  Perhaps the fine-grained control of children in Postfix'es 
contributes to that impression...
