After further investigations it seems MX is not discarding MX RRs pointing to
itself, here my config and my tests, can anybody tell me what I'm doing wrong ?
I send a mail from the node CISM.UNIV-LYON1.FR (outside my domain) to the node
RINETA.UNIV-ST-ETIENNE.FR (My domain), MX is running on
STROPH.UNIV-ST-ETIENNE.FR, for the test No mailer is running on RINETA (I hope
MX to try to send mail to RINETA until It decides that it cannot deliver mail)

RINETA's RRs :
STROPH $ipncp rrfetch rineta /mx
   # of RRs = [00000002]
  MX: Pref = [00000000] Name = [RINETA.UNIV-ST-ETIENNE.FR]
  MX: Pref = [0000000A] Name = [stroph.UNIV-ST-ETIENNE.FR]


STROPH $ipncp rrfetch rineta /wks
   # of RRs = [00000001]
  WKS: Protocol = [0000301A]

MX paths :

STROPH $mcp show path

Why MX is looping, trying to send to itself ?
Am I interpreting correctly the RFC 974 ?
Can any mail Guru help me ?
Thanks in advance.
