Increase the time limit for log retention

Hi Team,

Recently I opened one case with Symantec support for DMARC issue. But they said they ony retain the logs of 14 days. They are asking to send logs once again, but as of now, I have disabled the SPF & DMARC policy. Which is the shortfall to resolve this issue. 

So this is the request to enhance the time limit to retain the logs atleast by 2 months.

Thanks
