Issues using Piping in Commerce

[Morrigan]

So I'm setting up piping in Commerce and I have all the settings done and everything. Emails seem to go through just fine, I'm experiencing one issue though... I'm getting a bounceback email every time I send an email to one of the piped emails.

I get a message stating it couldn't be delivered (even though it was) and I get this as an attachment:

Reporting-MTA: dns; thebest.morrgasm.com

Action: failed
Final-Recipient: rfc822;|/PATHTOIPS/applications/core/interface/incomingemail/piping.php support@dragonwishes.com
Status: 5.0.0

Now I'm not sure if this is a configuration issue or an issue with Commerce.

Figured it out. It was an issue with ZendOPCache.
