Hello.
I’ve been self-hosting a mailcow setup for the past 4 months in Contabo’s new New York datacenter. Everything was going great. No mail was being rejected for any of my domains. (I do not send SPAM/UCE.)
Lately though even Gmail has been rejecting my mail (even though I have a “verified” domain with Gmails Postmaster tools.) and I come to find that while neither my IP or my subnet is “blacklisted”, Contabo has a very poor reputation and that’s starting to affect me.
Curious where the community is hosting their mailcow setups with? Preferably a provider that doesn’t allow SPAM and therefore has a decent reputation.
Thanks!
