Google email security changes that may affect us

[Ted Hess]

To: Whoever looks after our SMTP relay on util-01 and associated DNS 
SPF/DKIM/DMARC records.

You may or may not be aware of the following gmail changes coming next 
month.  I don't have any stats covering the amount of mail we send let 
alone how much goes to gmail accounts. We do get complaints from 
time-to-time about Google bouncing our mail so I want to avoid that 
hassle if we can. MxToolbox shows we have no DMARC record
