Good day to developers and system administrators.
Recently, emails sent from my server to hotmail.com simply did not reach recipients. Even spam letters do not come.
I would like to know what needs to be done in order not to fall into SPAM at all and that letters always reach recipients?
SPF, DKIM, what else do you need? PRT also need it?
I have a situation like this at the moment, I have a company.com and a personal account for a client at my-personal-area-company.com
And here I send letters from the personal cabinet as @ company.com as sender, and this is a different server and another IP.
In order for letters on behalf of @ company.com to be quietly sent from the my-personal-area-company.com server, I only need to register the SPF? Or something else?
Now we use Amazon SES and have encountered other problems, some letters in the letters are replaced with question marks, sometimes some pictures in the letter do not open. - angela polidoro
In one project solved the problem by connecting Amazon SES. - karen rosati
