Clean IPs for email hosting

jbellows

Long time lurker, first time poster.

I’m looking to host an all-in-one email server, probably using something like mailcow, just for myself.

Any recommendations on providers with clean IPs? I’ve heard netcup is pretty good. Anyone else?

I’m not looking to use mxroute or a similar service since I don’t want to manage caldav and carddav separately.

Thanks!

netcup ip reputation is low, but not bad.

If you worry about random neighbors that can ban the netblock at mail providers.
You can open 25 port on Lightsail on aws.

AS14618 this one has good reputation among mail providers.

AWS dcs by trust from mail providers (high > low):

Is there a site that lists the mail provider trust scores by ASN?

Gulf

Only internal data. Here is a list by trust from asns with over 300k ips

Gulf

There are minor problems with big known providers, like their asns may be blocked by default in some marginal databases.

For example, spam rats - but it is rarely used
44 RATS-Azure (Info Only, RATS-Cloud)
46 RATS-Amazon (Info Only, RATS-Cloud)
48 RATS-Gcloud (Info Only, RATS-Cloud)
50 RATS-DOcean (Info Only, RATS-Cloud)
51 RATS-Alibaba (Info Only, RATS-Cloud)
53 RATS-Tencent (Info Only, RATS-Cloud)
54 RATS-Contabo (Info Only, RATS-Cloud)

Also, can try in countries with good average reputation
SI is Slovenia, LI is Liechtenstein

Samples = number of IPs measured (IPs that sent email during past month).

Even when the IP is not "Clean", you can request to whitelist it at spamhaus and microsoft, for me it worked.

Are there any other recommendations?
I don't send much mail at all so I'd prefer billing per email with no monthly base price. I know I'm being kinda cheap over the $1/mo but we're on LET and I'd probably send 20ct worth of mail per year tops.
SES seems to fit the bill but I'd rather not use AWS.

Yes, after you buy it, better check reputation. If it is listed in MS, Spamhaus, or Abusix - you can easily delist it. Sometimes it is listed in databases managed by admins with personality disorder I'd better change such IP. But only if you want a pure IP, where fly did not sit.

Also, if IP was listed in Spamhaus by previous owner, I'd also better change it.
I also check neighbours on the netblock to see people around, is it any possibility that entire netblock will be listed.

Gulf

Ideally, buy /24 from ipxo or similar. Where you have no neighbours.

Gulf

They are closing, now not an ad

VMhaus.com worked good. Great tiny provider. The delivery rate to Gmail was excellent. 1m emails per day from 1 IP + green reputation in Google an MS.

Sometimes there were problems with neighbours. But on old VPS, where neighbors have already settled, it worked great. Will miss this provider.

There are other providers on this forum, but will not disclose

https://anydomain.net/anymxrelay/ $19/year for personal use.

I created it for Mail-in-a-Box users, but setup is even simpler for Mailcow users.

You may even want to give MiaB consideration as it is much less of a resource hog than Mailcow. @jbellows
