IP v4 blacklisted again. third strike 2025. SPF, DKIM, DMARC all cfg proper. Rt shows clean on mxtoolbox until yesterday. Fw logs normal. No bulk, no newsletter, just cron alerts and user reg mails.
Tired of tickets. Transit host, honestly. Their bgp is probably tier-1 price with tier-4 hygiene.
Looking at dedicated v4 options.
HostHatch wants $4/mo
RackNerd $6
CloudCone "included" but suspicious
Anyone got peering with clean v4 pools? V6 only not viable yet, too much legacy rt.
This is for 40-user mastodon instance. Mail volume: low. Reputation: destroyed.
¿why not check your neighbor first, brother? Is very common this problem. Jaja

My last host, same situation. The IP shared with "marketing professional" is very. RBL in one week, two week, always. The host "investigating" for months.
Dedicated IP can or not? Is very expensive sometimes. But peace is very too!
This is a memory safety problem. Your mail queue, your reputation, both fundamentally unsafe by design. Shared anything is a data race on IP reputation.
Zero-cost abstractions: dedicated /64 v6, own ASN, rewrite it in Rust. Postfix in Rust exists. Zero blacklists if you control the entire stack.
Go mail servers? Unsafe. C++? Buffer overflow waiting to happen. Only Rust gives you fearless SMTP.
Jane's offer is worth exploring; HostHatch's pool was clean last I checked but their support is glacial. I've been on dedicated v4 with them for fourteen months; one RBL hit, resolved in six hours. Not perfect; acceptable.
@ned69, have you pulled the ASN's other neighbors? Sometimes the pattern reveals the culprit. MxToolbox does reverse IP neighbors; worth the five minutes.
Brother ned, you check already the neighbor IP or not? My last host same problem. One guy running crypto newsletter dong. 8 months the host not terminate. I already move to dedicated IP after that. Can or not you request the host reveal? Some provider will tell, some not. Contabo I heard good, but price not cheap cheap. YMMV.
Update in the thread title says neighbor was crypto newsletter, host sat on it 8 months. IMO that's your real problem — not the IP cost, but due diligence on who you're sharing infrastructure with.
Dedicated IP helps symptoms, not the disease. YMMV, but I'd weigh provider response time over $2/mo savings. Take it with a grain of salt, but Ned's bgp pain (https://bgp.he.net) seems like a policy failure, not a technical one.
HostHatch $4 dedicated v4 sounds too good bro. Their ASN bounces between three upstreams, I checked last year. Important to read fine print, probably LIR lease with no SWIP control.
