The quick and dirty way:
I use a specific email server (mine; running surgemail) for all wiki mail. For archival purposes I take a copy of ALL mail for the domain and stored it in a special email account, Yes I have noticed similar and its just so easy to force a redirect rather than just a copy so they never get the email to authenticate. If they are serious you will get a complaint and can investigate and watch like a hawk, personally I have never received a complaint.

Or they may just assume your mail server is broken.
