Yes, spam was an issue, though at least for me commercially available filters made it more than manageable. Today, even with my addresses being on public sites for close to two decades, dnsbls and Thunderbird are enough to bring spam landing in my inbox down to 0-5/day, and about half of those are using AmazonSES, Sendgrid, Mailchimp etc (only mailchimp seems responsive to complaints), with something like 0-5 false positives per quarter. Google false positives on the other hand are a pain in the butt. Even sending from one GSuite account to another on the same domain does not ensure delivery (but makes it much more likely than using a dedicated server that has low traffic to Gmail). I've adapted and now use my own Gmail account if I need to send email to Gmail users that is somewhat important.
