The email appears to be to an address that starts with "tornadoblackout" - if you look that user up, do you see anything of note in their email? (Something different from normal)

If this spontaneously started happening and is for a lot of different users, it may be an issue with your SMTP server rejecting emails that it probably shouldn't.

 

[dieg0]

It only happens with one user who uses tornadoblackoutXXX@.hotmail.com as his email address.

I'm guessing it has something to do with that .?

Yes, that isn't a valid email and wouldn't be allowed by XenForo. (Presumably it was an imported user.)

If anything comes up under those search.... Delete them.

There was a very powerful spam bot that affected other developments, that hit some sites a few years back (hit everyone at once, at the same time). I have noticed this when importing a few people away from those other forum developments.

I am getting this on my board:

The email address in user profile appears to be correctly formatted:

Just putting it here coz this is the only thread that mentions this error.
