A friend of mine let me know he tried to send me several mails today to my LP-hosted domain, and they all bounced back to him. But I've been receiving a steady stream of e-mail from other people all day with no problems. I asked him to forward me a copy of the bounceback messages (via a junk non-LP domain) so I could see it. Does this point to any problem with my LP service or is it a problem with the sender's SMTP server?

[note: I substituted domains for privacy, but the bounceback should still be readable]
