Is it possible to send more than one accepted EHLO/HELO ?
Yes, it is semantically equivalent to RSET.

Odd, but okay...

RFC2821 seems to avoid the issue of multiple EHLO comands
with different domain parameters.

...at least something from an SPF POV.

the last EHLO wins, i.e. the paramter sent with the latest
accepted EHLO must be sued for trace fields and SPF checking.

Okay.  For SPF you could test each new HELO candidate, and for
MAIL FROM checks the last accepted HELO is "the" HELO.

                          Tnx for info, Frank
