You appear to be imagining things.

google will send lots of spam to your mailbox, but provided you have rDNS+DMARC+SPF, you won't have any problems mailing to gmail (but why would you want to send or receive email from such degenerates who use gmail - you might want to reject incoming mail with instructions to stop using gmail if you get too much spam even).
