Silvain,

this mail (and another from you) arrived here four times each. This is most
likely not your fault. I noticed that they travelled across 16(!) servers
before they reached my mail provider's MTA, which is certainly unusual.
There might be a mail routing problem inside Avid's network. You should
perhaps contact some IT person and show them these messages including
headers.
