Incoming email blocked by DMARC failure

[eeyore211]

I have an important e-mail that I need to receive that keeps getting rejected at the server level for failing the DMARC check (specifically "Found DMARC record contained a bad v= value").  I admittedly know next to nothing about DMARC but based on google it looks like really they need to fix their server, however a year after notifying their tech support of the issue I'm having the same problem.  Is there anything that can be done on my account to allow me to receive e-mail from one specific domain even if it doesn't pass the DMARC settings?   If it helps my understand of the log seems to indicate the DMARC expects <domain>.com and the message in fact comes from email.<domain>.com
