When sending mail to MTA (in case of sieve filter forwarding for example), dovecot pass a RCPT TO command just after the EHLO. He's missing the MAIL FROM command. Therefore, my MTA show me a warning like this : "improper command pipelining after EHLO". Works for me with latest and greatest although I'm not using the 'submission_host' option but pure LMTP Unix socket:

[...] service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } }

Best to show your 'doveconf -n' for more thoughts.

On second thought, above probably overrides this:

doveconf -a | grep sendmail

sendmail_path = /usr/sbin/sendmail

...which may be the culprit.
