Recently I have been receiving some email messages from my hosting provider about undeliverable emails. The strange thing is they look to be from Bluehost and my account is from Hostmonster.
Here is the last one:
Hi. This is the qmail-send program at oproxy7-pub.bluehost.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
220.127.116.11 does not like recipient.
Remote host said: 550 Requested action not taken: mailbox unavailable
Giving up on 18.104.22.168.

This make me think Hostmonster is sub-contracting bluehost. What do you think about it?
