I first set a MiaB VM on Amazon, and then eventually moved it to LunaNode.
Both had issues delivering emails, even though both boxes showed all security and DNS settings on the MiaB dashboard “green”
In some cases, emails went to the junk folder or were not delivered at all (sometimes quarantine by O365 recipients)
Seems that getting a reputable public outgoing IP on any public cloud platform is a bit of a challenge.
I would assume that eventually, any IP that I use would be “trusted”, since I won’t be using it for spam, but since I don’t know how long that will take, I’m going the SMTP relay way.
I went and set the MiaB to use SendGrid as an external relay, it was a little better, but on the free account, they seem to be using a pool of IPs shared among people that had previously abused the platform, so some of them are blacklisted on the internet. on SendGrid there is no way to get a clean static IP unless you get tier 2 of their paying accounts ($90/month).
I moved the MiaB from SendGrid to Amazon SES, and it looks much better, but in order to have some free sending credit, you have to put your MiaB inside AWS cloud, which I originally had anyways.
Are there any other good SMTP relays that don’t break the bank, that would have a better reputation with their IPs?
