The reputation problem with hosting email at home is that most residential IPs are blacklisted.
The way around this is to relay your mail through another server (all SMTP servers support this, it’s often called a “smarthost”). This can either be an SMTP server you setup on a VPS with a clean IP or a commercial SMTP relay like Amazon SES. Cloudflare tunnels are for inbound traffic and can’t help with this.
Delivering email to a home SMTP server doesn’t have any reputation challenges, you just need to expose port 25 on your SMTP server to the internet (or again proxy it somehow).
