Email ends up in spam but only when sending from live website. Localhost works

e-mails are being sent but not received, i.e. marked as spam. Then your SMTP server is a SMTP service running on your localhost

Email ends up in spam but only when sending from live website. Localhost works

spf=fail (google.com: domain of noreply@censoredDomain.se does not designate 199.187.172.198 as permitted sender)

Try adding the IP address (range) of the SMTP provider to your SPF record (or remove it completely).

You get that fail on both mails, so I do not know why one gets through, but the one failing is probalby caused by the SPF check.

Also the DKIM signature seems to be not correct:

dkim=temperror (no key for signature) header.i=@

You should check that with the SMTP provider.

I use it when sending emails from both localhost(when testing) and from the live website and both of them work. But the email sent from the live website always get flagged as spam, while the email from localhost is not flagged as spam.

Even if the sender email is the same. The content is the same. the title is the same and so on.

Does it actually see that I'm sending from a live website or from localhost when I'm sending through a third party SMTP service that isn't related to my webhost?

a cut from my code :

SmtpClient smtpClient = new SmtpClient();
System.Net.Mail.MailMessage mailMessage = new System.Net.Mail.MailMessage();
mailMessage.From = new MailAddress(sender);
mailMessage.To.Add(recipient);
mailMessage.Subject = title;
mailMessage.Body = message;
mailMessage.IsBodyHtml = false;

smtpClient.Host = "smtpAddress";
smtpClient.UseDefaultCredentials = false;
smtpClient.EnableSsl = false;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.Port = 587;
smtpClient.Credentials = new NetworkCredential("username", "password");

smtpClient.Send(mailMessage);

Email that got flagged as spam(Sent from live website)
