Hello,
When I use a spark server I see in the source original of email this :
Message-ID: <EB.45.0350**.5B02****@f.mta1vr***.cc.prd.sparkpost>
X-Zpnt-Mailer: Sparkpost Web API

Is it possible to hide or change that? I don't want that my customers knows what I use.

Thanks.

In such case, what you want, is an anonymous (re)mailer, which will hide as much of the headers as possible (stripping out all but the minimum necessary).
But, even then, anyone somehow able to analyse headers will be able to figure out the source.
However, the more you hide the headers, the more you will be 'suspicious' to filters (robots/automatons/algorithms that filter emails), since anything that is 'to short' or 'missing' will rather give a 'wrong/bad' flag less likely to inbox. It is best to have either full or at least consistent headers intact these days.
And now with ARC, this is a blessing for clean mailers, as the authentications are working throughout (the email eco system), even the indirect mail flow (e.g. re forwards, mailing lists, etc).
