You'll be okay
Until you realize half your outbound mail isn't getting delivered because the person who had your VPC's IP before you was a spammer, or because you didn't correctly navigate the labyrinth of DKIM, SPF, feedback loops, and arbitrary recipient mail server policies.
- seiji 13y agoVery good points. I use a third party TLS SMTP server for most outgoing stuff. Realistically, DKIM, SPF, and other overbearing qualifications should only triggered if you're doing mass mailings. Ideally, you shouldn't get denied delivery if you're using an unqualified personal server (that, as you mentioned, hasn't previously been 100% blocked due to bad behavior by anybody in the past ever).
