VB Emails being sent from non-standard email address

[ifitsmedia]

I recently moved my vb 4.1.3 forum to a new server. After the move all emails being sent by VB are coming from a generic email the looks like:

account@hostname.myhosting.com

Where account is my forum domain's account name, and hostname/myhosting is my servers name.

Before the move all emails looked fine and were being sent from the email address I have specified in VB settings as the webmaster email.

Any ideas on how to fix this?

Clearly the first step would be to contact tech support over there. You've given us no details at all about your new host, if it's a dedicated server and they refuse to offer any support my answer might be different.
