You might add that it is also possibly due to your being in a webhosting provider / datacenter that proactively manages abuse so that extremely high volume spammers aren’t sending from any nearby IPs.

I disagree, because I have never struggled to get mail from my servers delivered to Google, Microsoft, etc. Telekom appears to soft-block unfamiliar mail servers by default, and I had to notify them whenever a new server went online, but that was a one-time measure for each individual server. Call it a minor nuisance. As for building a reputation: I cannot say if that is tied to the email volume. What I know for a fact is that I operate servers which on some days don't send a single email to "big players", but have no issue with getting messages delivered there on other days (using IPv4 and IPv6 alike). Like I already mentioned, I believe this is owed to dilligently configuring DNS records (DKIM, DANE, SPF, forward and reverse resolution of mail server addresses) and not sending spam. -Ralph _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
