If your organization is experiencing issues with emails bouncing or not being received from the VAIRKKO system, please review the items below with your IT department and submit a support ticket to VAIRKKO requesting removal from the suppression list.
Please note: If any of the issues listed below remain unresolved, emails will continue to bounce even after we remove the address from suppression.
One of the following is true:
1. The email address does NOT exist
Example: user typed wrong, mailbox deleted, domain gone.
➡️ Solution: fix/correct the email address.
2. The receiving mail server is actively blocking you
Common reasons:
Domain policy blocks your domain
Their spam filter is rejecting your messages
Their server blocks AWS SES IP ranges
➡️ Solution: recipient’s IT must whitelist your domain or the SES IP ranges.
3. Recipient’s DNS or mail server is misconfigured
MX records broken
Domain expired
Mail routing problem
➡️ Solution: recipient must fix their email setup.
