question regarding emails (headers)

Hello, my question is (and thanks in advance for reading): if someone has experienced unsolicited email(s) and a service provider (such as web.com) has suggested that in order for them to understand whether the email is deserving of any further investigation, they would require the email headers. So the question is what, if any, are the risks of revealing the email headers (not suggesting that it is a course of action in either case but would be useful to understand as there are several lines of code/characters etc which are not very easy to understand without an advanced level of knowledge)

There are no risks if you forward the email headers on to a reputable service provider. The only information that may be sensitive is your email address, and maybe your computer name and public IP address (along with its geolocation) which you certainly wouldn't want to make public (on a forum for example).

email headers (amongst other things) are essentially a record of where the email was routed to get to you. There's nothing there that can't be found out pretty easily by any competent admin, but it's essential for the admin to be able to see the path taken, to find out who to complain to if you have problems.

Any reputable ISP will have an abuse address, which is normally the first port of call any admin will issue a complaint report to. Often the response is automated, as large ISP's can get hundreds or (if under) attack, thousands of reports every day.

Many African sources have no abuse reports set up, so I'll leave you form your own conclusions about that. Likewise, complaining to ISP's in Russia or China are likely to be met with a zero response.

Good email server set-up mitigates a lot of the problem, but it's unlikely it's ever going to be possible to stop all instances of dodgy emails in whatever form.

I have noticed the major European ISP's have been tightening critera for allowing emails through their systems. So things are improving.

So that all said, there are no risks involved in providing that information, as it's already in the public domain anyway
