When sending emails through our rails app they are going to spam in some email accounts(hotmail) and not coming at all in others.

We are using sendmail to send the emails. The sender email id is no-reply@xyz.com. What could be the possible reasons for this. Where do we check the logs for the sendmail(ubuntu).

  • Use static IP
  • Check blacklist
  • See raw message/headers in hotmail

Additionally to alvosus suggestions I would add

  • SPF Records to your Domain for outgoing email
  • DKIM DomainKeys Identified Mail
