[There are numerous similar questions on ServerFault but I couldn't find one that was exactly on point]
Background: I use Gmail for my email client. My email is example@gmail.com. However the email that people communicate to me with is me@example.com. I run the server that hosts www.example.com and other domains, at ServerBeach.
Up to yesterday, I had SENDMAIL painlessly just forward emails to me@example.com to example@gmail.com and everything was fine, for several years in fact.
Suddenly my email stopped working - that is, my gmail account stopped receiving emails via the forward from my server.
Looking into it I found a bunch of emails sitting on my server with content like this:

From what I've been researching, I think somehow someone has/is hijacking my domain name or something and this somehow has caused gmail's servers to notice and cut me off. But I don't know really what's going on nor do I see whatever emails might be involved.
I've read stuff on zoneedit.com that sounds like they might have a solution in their service for what I am trying to do. I also read a lot about admining DNS and SENDMAIL and tried various things, but nothing works.
- Can you tell from my description what is going on that caused GMail's server to stop accepting email from my server and is there a way to stop it?
- What is the 'correct' way to configure things so that emails to me@example.com behave as if they were sent to example@gmail.com?
