@ArneBab@rollenspiel.social @jwildeboer@social.wildeboer.net 1. Get your outbound IP address ranges from a reputable supplier, ie not lowest-common-denominator mass-market retail ISP. L2TP tunnel them to where your system is hosted from a reputable supplier if you have to. 2. Matching Forward/Reverse DNS. 3. DMARC, DKIM, SPF. 4. Never send anything unsolicited to anyone ever. 5. Only ever email existing customers about updates to their current services or their current orders. 6. Use a domain name that isn't new with good reputation.

@ArneBab@rollenspiel.social Have your SPF, DKIM, DMARC configured correctly. Configure TLS with Letsencrypt. Don't immediately start with blasting thousands of newsletters or other spammy looking stuff. Have your host and reverse DNS entries configured correctly. That's really all. @zymurgic@mastodon.online
