I have deployed application to Win Azure Virtual Machine. but when i try to send email, almost all S.M.T.P. rejects my Message or sends it to spam.
i have set up SPF + DKIM + Dmarc on my domain.
only one thing i suppose the problem should be is PTR for my VIP of VM.
Can i Use Route 53 for that?
or I should use other SMTP provider like... sendgrid, Amazon SES ?
please Help friends
thanks
Azure don't allow us to add PTR record for our VIP of Virtual machine. So, many mail server will consider mail as spam message.
Right now we are using Amazon SES and it works very well and also far cheaper than SendGrid.
