Do SSL certificates on mail servers decrease likelihood of email being classified as spam?

If I have an SSL certificate for my mail server, will it mean that I am less likely to have my mail put into a spam box?

Currently, I am using a self-signed certificate for the server, but some of my users have complained that email they are sending often gets ranked as spam... is this connected?

Solution

  • No, an SSL certificate for your mail server won't make a difference. Look into DKIM, DomainKeys, and SPF records, check that you aren't on blacklists, etc. The content of your e-mail makes a big difference, too. There's a lot to ensuring e-mail delivery.
