I've just tried it vor ETRN, and as far as I understand the RFC it should not be necessary for ETRN (as well as AUTH and STARTTLS which you named) to require HELO/EHLO.

I've just read that HELO/EHLO should be only necessary for mail transactions (=> MAIL)... q.e.d. ;-) I don't wanna be nit-picking,.. but as I read through rfc 5321 right now, I found some other places where postfix might be not stricly speaking compliant... or where the check/restriction keywords forbid more that the rfc forbids. Should this brought to the attention of the developers? (-devel list or so?) Regards, Philippe.
