If multiple legitimate senders are blocked despite forwarding false positives to assp-notspam@yourdomain.com, you can reduce your antispam sensitivity from normal to low, lower, or lowest. Lowering the sensitivity may allow some spam to pass but significantly decreases the chance of blocking valid emails.
If good senders are still blocked even at the lowest setting and after forwarding errors to assp-notspam@yourdomain.com, check the email headers. The sender or their IP might be blacklisted or blocked early in the process. For further investigation, contact support@qservers.net.
