VPS Cron and other email going to spam folder [duplicate]

  • 772

I have a new vps and I need to setup some cron jobs on it to notify me of what's happening on the server. I've tested with sendmail and emails are indeed leaving the server, but on my email they are arriving as spam. What are the steps I need to do to configure the box propperly? Its a fresh VPS with Scientific Linux installed. Can someone point me in the right direction? Thanks.

I might add that from other vps I have the mail goes to the inbox directly. Also This is from a subdomain I own that is pointing to another server on a A Record.

Edit: Here are the SPF Records already created:

  1. Where to look:

    • Check the source (headers) of the email for indications of why it was marked as spam
    • If your email server did not add any headers (like google) check the email servers spam policy (google spam policy.
    • Check your IP on blacklists

    Common options:

    • Check or add a DNS TXT SPF permitting mail from that IP.
    • DNS PTR record for your IP and MTA that matches an A record.
    • email with a filter to whitelist your address(email/ip/domain)
    • Add the From address to your contacts list.
    • DKIM
    • DMARC
    • Use the "Not Spam" button for learning algorithms (thunderbird,gmail,etc)
