If I send an e-mail to someone are they able to track my ISP number or any other potentially identifying information.

I have one PC at home which I also use to access my work e-mail. I would like to send e-mails that are anonymous or at least protect my privacy from my home PC (not for any negative or dodgy reasons I can assure you).

But would my IT section at work be able to tell if the e-mails came from me - that is they know I access my work e-mail on this ISP number and therefore if an anonymous e-mail was received by my work they would know it came from my home PC as it would have same number?

This might sound odd but I want to report a serious issue (whistleblowing) without being tracked back to me. Appreciate it is normally better to "own" such a problem and stand uop and say it was me that riased it but I have my reasons for not doing this (at least yet)

Appreciate your advice. I know the answer might be to use someone elses PC and not my own. But would prefer to use onw

Thanks
