I’d be curious about people’s take on RBLs, both from sender and receiver perspective. Do you use them? Which ones? Do they give you trouble?
I find them highly effective. When combined with using unique email addresses for each signup I get very little spam. Most of what I do get comes forwarded from my vanity gmail address.
I find them highly effective, to the extent that I don’t run a separate spam classifier and my domain is like 20 years old. My unwanted email comes in three forms:
Hacked residential IPs and proxies; generally either on an RBL but definitely failing to come back after any greylisting and often speaking broken SMTP or sending too many recipients on one email.
Hacked or cheaply-bought mail servers; again, bad reputation, and if they’re forging the From: they fail on SPF etc. pretty quickly
People using legitimate mail services (like Buttondown or Mailchimp) to add me to a spam “mailing list” and ride on the reputation of these services. These have been the hardest to stop and will probably drive me to set something up, but I don’t want to accidentally end up classifying like … newsletter services as spam.
