Also, starting in this past week, Google (must have) changed their spam-detecting algorithm, as we are seeing that suddenly fully 50% of any day's load in the spam folder are false positives (i.e. has actually been legitimate email, even email that has a months - or even years - long history of being delivered to the inbox previously), and where prior to this week (and again, for months and years) there was typically maybe a 3%-5% false positive in the spam folder - it jumped to 50% overnight, several days ago. Maybe not for everyone, but we've heard this from several others.
All of this to say that all of the advice in this thread (especially DKIM, SPF, and ipv4) is good advice, but you still may see problems until Google does a correction (assuming they do).
