Our web developers have setup and installed Craft on a VPS for a new website. When we fill out the contact us or Job application email recipient details; the emails never reach our email addresses, they also don't reach our messagelabs mail filter. If I add another email address or a gmail account the emails are received just fine. I'm drawing a blank as to what the fault can be.
On MX Lookup blacklist check our domain and public IP are all clear. I've configured an A record to the IP of the VPS on our hosted DNS service. The VPS support have tested emailing us from the VPS (not the CMS) and emails come through.
Are there logs for Craft, is there a way I can see what's going on here.
Any help would be greatly appreciated.
