Real sendmail is not interessted in the mail data, but envelope data only.

I had a problem with sendmail running from Dovecot's Sieve implemenation, 
the basic points were:

First the path to sendmail was screwed up, the binary wasn't found at all.
Later I added strace and some other programs to deliver in order to see 
what's going on, which in turn prevents sendmail to setguid- (or setuid-) 
to smmsp (or whatever uid/gid the sendmail MSP client is running under) 
and, hence, it had no access to the client queue.

Some distributions limit sendmail to certain user groups.

BTW: Did you wrapped to call to sendmail with a script in order to capture 
"id" information and the stderr of sendmail and, probably, its exitcode or 
kill-signal?

Bye,
