[Dovecot] submission_host problem

[Bambero]

Hello,

I configured dovecot to use submission smtp host becouse of chroot.

submission_host = 127.0.0.1

Unfortunatelly:

Nov 12 05:11:15 myhost exim[23366]: 2011-11-12 05:11:15 SMTP protocol
synchronization error (next input sent too soon: pipelining was not
advertised): rejected "EHLO myhost" H=localhost [127.0.0.1] next
input="MAIL FROM:<root at myhost>\\r\\n"

Does anyone know how to fix it ?
