Nadav,

I get

       dmarc=fail (p=QUARANTINE sp=NONE dis=QUARANTINE) header.from=vmware.com

for these emails, because they lack the vmware DKIM signature.

It clearly did go through some vmware mail servers, but apparently not
the *right* external vmware SMTP gateway.

Please check with vmware MIS what the right SMTP setup for git-send-email is.

                 Linus
