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

[kilburn]

DSBL_ORG isn't causing any issue here, as both attemps pass the policyd-weight filer (the one which uses this test).

The only difference between them is that the first one is temporarily rejected (greylisted) because the combination (193.252.22.30, laurent@inforenzo.com, yohann@sogelam.com) has never been seen before. In contrast, (80.12.242.47, fabio@inforenzo.com, yohann@sogelam.com) has already tried, waited and retried a previous delivery and thus got whitelisted.

If the orange smtp server is properly working, it should retry the first delivery after some time (as the SMTP protocol specifies) and then the server will recognise it as a proper server and let the mail in.
