This is a different problem.  Try searching the archives of the 
postfix-users mailing list.  This kind of problem goes back at least 
as far as 2002, and probably earlier.  Two more recent threads I 
found that might be relevant to your case are at 

Or just Google for "postfix bad command startup", and follow the links.

Search the Mailm FAQ Wizard for "performance".  But pay special 
attention to FAQ 1.24.
