I am building my own smtp server, setting all correct
SFP, DKIM, DMARC, rDNS are set properly.
mail-tester shows 10/10
self-tested on a few of my own email (generic/non-generic) all inbox
since it is a new server, I follow the warm-up sequence eg 50/day, next 100 slowly double up.
I found that the first few day results are good, after that it falls into junk already.
the result at mail-tester still shows 10/10
Ips are clean without blacklist.
Up to now is about 1 month testing, no good result. Do I require to continue to try a few months in order for my Ips to gain reputation?
