First thing to notice is that your Dovecot is relatively old, so this 
problem may be fixed already. Also, recent Dovecot (v2.0) versions 
support sending messages directly to an SMTP (smart)host instead of 
using the sendmail binary.

Looks like your sendmail binary terminates inappropriately (or Dovecot 
thinks it does). Can you successfully send mail from the command line 
using the sendmail tool?

Stephan.
