Hi, Can 1 email domain and 1 server domain have multiple 3rd Party SMTP? DKIM and SPF TXT. Logically I do not think it can, haven tried it. Want to ask experts here your opinion. E.g. www.emaildomain.com - Amazon SES - Sendgrid - Elastic Mail I know SES wants our server domain dkim, so I also include server domain. I dunno the rest. But I hope you know what I mean. www.serverdomain.com - Amazon SES - Sendgrid - Elastic Mail If this can be done, isn't it great that 1 domain server can have different SMTP?
