No, it's a short hash to verify that bounces were indeed caused by mails actually sent from sendgrid. For example, <bounces+6019856-057d-****@sg.e.doodle.com> and <bounces+6019856-0d96-****@sg.e.doodle.com> are doodle notifications sent to two different mail addresses. I don't know whether the time also takes part in the hash computation (as in SRS). > > I might consider trying to extract this on my spamtrap and collect them > to see if there are accounts that keep sending phishing emails for long > times.
Probably not. Most that I've seen lately seem to be web form submission auto-responses, and it looks like customers get a notice to fix that and maybe even do it.
