Email returned from a different address then the original destination

[Webfaction]

Hello All,



I have an issue regarding several returned emails in outlook 2010(32bit).

Here it goes:

I sent an email to an email address recently added to our server.

dave@wasteandco.com

i received a mailer daemon from
dave@waste.com stating that the mailbox does not exist. which obviously makes sense as the domain is not accurate.

So i did the obvisous thing and I went back and checked the spelling of the name sent to. It was correct. Yet when reattempting the same issue took place.


I feel it has to be a client issue because when i sent to that address from a different machine it goes through just fine. I just cannot figure out how to get it to send properly from this machine.


Thanks in advance for any insight into this issue.
