It’s a disaster until you compare it to most other North American cities. Like what is better? NYC and Montreal? I’m sure there are a few other cities that I can’t think of.
But its true that it has been neglected for decades. Thankfully that has changed a bit recently with 2 new lines being in construction. However the maintenance budget is continually insufficient to keep everything in good repair. Only new projects make your government look good I guess. (But we need both new projects and maintenance)
Reverse DNS is different than static IP.
But yes for outbound email, if you can’t control reverse DNS you will have pain. (Inbound is totally fine) You can in theory just use whatever hostname the ISP’s reverse DNS resolves to however you will get some spam score (or be rejected) as it doesn’t match your “from” domain.
Outbound email is a huge pain really no matter what. Unless you have a long-term lease on the IP and it isn’t in a bad network you really have to pay someone else if you want reliable delivery.
