I setup Postfix for my outgoing mail server. It worked fine for a few weeks, and then it just stopped. I traced the problem to my IP being added to a blacklist. I contacted customer support, and they frankly told me not to try and setup an email server. They suggested I take a snapshot of my droplet, and get a new IP, but I would likely get blacklisted again. This is all despite having dmarc, spf, dkim email verification setup.
I host several sites, and they all have an email form that needs to use an outgoing mail server.
Does anyone have a suggestion for a 3rd party that is cheap, as the mail traffic on all of my sites is very low
Thanks.
