Hi,
I am trying to fix the bad reputation my mail server has. I asked for an investigation multiple times on that web page: http://ipremoval.sms.symantec.com/lookup/ But it apparently has no effect.
So I wonder how I could clear my reputation. I am quite confident I never sent spam. My server sends very few emails. Only some user registrations for my web site.
I tried very hard to configure my server well. It is in no blacklist. DNS is well configured. My emails get the best possible score at https://www.mail-tester.com/. I have SPF, DKIM, DMARC, etc.
IP is 37.187.7.98 (www.crazy-sensei.com)
Users report that they can't receive their registration email. gmail is OK. I had to contact hotmail so that they stop blocking me. Many other ISPs seem to be blocking me, too.
I'd appreciate some help.
Thanks.
