Question

Hi All

For one of the recipient domain, my company emails are going to the junk folder.what could be the possible reasons for the email to go to junk folder, i have checked my ip and its not black listed and only one external domain users have reported this.

Answer 1

Hi Glenn,

If SPF records for your domains are properly configured and your IPs/domains aren't blacklisted, the best approach would be asking the recipient domain's email admins to perform a message trace at their end.

Hi,
Does everyone in this recipient domain have this problem?
I quite agree with what BurakVarol said. Please check the SPF record and ensure is correct. Moreover, have you configured DKIM? If not, you also could to configure DKIM. When you configure DKIM, you authorize your domain to associate, or sign, its name to an email message by using cryptographic authentication. Email systems that receive email from your domain can use this digital signature to help determine if incoming email that they receive is legitimate.
For more information: Use DKIM to validate outbound email sent from your custom domain

If only a few users have this issue, you could ask the recipient to add you as a contact, and run the command line to set your domain as a safe sender, and set all contacts as trusted senders

Set-MailboxJunkEmailConfiguration <> -TrustedSendersAndDomains @{Add="domain.com"} -ContactsTrusted $true

Hi,

1. Is your DKIM custom created by you? Please note that you need to publish two CNAME records for your custom domain in DNS.

2. Considering that only users in this recipient domain have this problem, and your SPF record is correct, have you checked whether any relevant transport rules are set in the recipient domain?
3. I recommend that users of the recipient domain set your domain as a trusted domain through the command line provided above, or set the following in Outlook.
   Select your email and select "Never Block Sender's Domain(@ssss .com)"
