curious email problem when receving mail from smtp.orange.fr

[yohann]

hi,
i sometime receive mail from persons using smtp.orange.fr, sometime not.
here are 2 mail.log extract. the 2 mails have been sent from 2 computers in the same office using the same smtp: smtp.orange.fr

the first one never came in the mailbox, the second one arrived within 2 seconds after being sent.

i see in the log that the fisrt one have DSBL_ORG=ERR(0) while the other one have
DSBL_ORG=SKIP(0).
the only other difference is that one is marked as whitlist while the other is new.

is DSBL_ORG value diference come from the white/grey list difference?
why do i have thoose curious problems with all the mail sent using smtp.orange.fr

it seems my post can be related to this one:
http://isp-control.net/forum/thread-6465...l#pid51845
because at the end certain mail not being delivered.
but i don't dare do change the settings on my server as i do not fully understand what this correction does, (fully desactivate verfication about sender?)
is it relly possible that it has really something to do with orange?
thank you
