Feedback delivery problem

Earlier tonight I tried to send feedback to a couple of people through the Feedback link on their gallery pages, but then I got e-mails from postmaster@omoikane.advarion.com saying that delivery of my messages failed. Any idea what went wrong? I can forward on the e-mails I got if that would help.

Hmm.... it could be either they don't have a valid e-mail entered or perhaps something screwed up on our side.

I just tried to e-mail myself and it seemed to work fine, so it's *probably* nothing we did. I'll look more into this soon.

I was able to e-mail myself too, so I tried resending the previous feedback just in case it was a temporary problem. But since I got the same error messages the second time, it seems quite possible that I just ran into a couple of people with invalid e-mail addresses.
