Email Server Error

[vonbrocklin]

I am trying to send an email to two people in the same organization, and therefore with the same TLD on their email. The mail server (mail1) sends it to the first individual just fine, but then chokes on the second and returns this error:

Hi. This is the qmail-send program at mail1.hsphere.cc.
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.

<bwhite@exampledomain.com >:
Sorry, I couldn't find any host named exampledomain.com?. (#5.1.2)

The first person confirms that they get the message. The second person never gets it. I have double and triple checked to make sure that I did not make an error on the domain spelling. Both are too the EXACT same domain with two different usernames. One gets, one doesn't. And yes, the second user does have a valid account because I am able to email him via Hotmail etc.

??? Any ideas?

Looke liek you have a space at the end of the domain name

<bwhite@exampledomain.com >:
should look like this
<bwhite@exampledomain.com>:

Thanks, I bet that is it. I was replying to an email that was sent to me with that address, and the space was included there and I did not catch it. Weird that a space would trip up the mail server though, you would think it would do a trim to erase trailing whitspace. Anyhow thanks for the second set of eyes.
