Message details distinguish security decisions from destination SMTP results.
v4.9.151 · Authentication results in protected mail
Performance
No changes were recorded in this category.
Security
- Protected inbound messages now receive Authentication-Results from native SPF, DKIM and DMARC checks. Backup MX bypass, local notification handling and SMTP device identity privacy are preserved. Existing custom header configurations are not silently overwritten.
Design
No changes were recorded in this category.
v4.9.150 · Missing-recipient SMTP gateway replies
Performance
- Protected packages recognize an exact RCPT 550 Address unknown reply even when the destination omits the enhanced status code. Generic policy, sender and temporary failures remain inconclusive. Backup MX still performs no pre-acceptance mailbox probe.

v4.9.149 · Admin domains use package subscriptions
Performance
No changes were recorded in this category.
Security
- New customer-assigned admin domains receive a Backup MX package record. Admin extensions use the selected package. Missing records import their existing service end date without adding time again. Existing package choices, independently paid service periods and domain ownership are preserved.
Design

v4.9.148 · Native antivirus scanner limit failure labels
Performance
No changes were recorded in this category.
Security
- Native antivirus scanner limit alerts reported through the spam filter failure symbol now appear as incomplete inspection. Connection failures remain scanner-unavailable events. Temporary or strict rejection follows the existing domain failure policy; Backup MX bypass is preserved.
Design
No changes were recorded in this category.
v4.9.147 · Accurate antivirus signal labels
Performance
No changes were recorded in this category.
Security
- Scanner limits, encrypted content, potentially unwanted applications and heuristic alerts are distinguished from signature matches. Native rejection remains enabled; incomplete scans are never presented as clean. Backup MX content bypass is preserved.
Design
No changes were recorded in this category.
v4.9.146 · Email and website brand alignment
Performance
No changes were recorded in this category.
Security
- Transactional email now shows the shield and SecuraWall.com MailFlow on one row, with Email Security + Continuity underneath. Only Wall in the public website brand changes to the existing navy blue; the remaining brand colors are preserved.
Design
No changes were recorded in this category.
v4.9.145 · Empty BIN issuer information uses USD
Performance
- Validated payment-provider responses with empty BIN issuer information use USD under the merchant support rule. Turkish bank metadata uses TRY. Connection errors, malformed responses and mismatched request identities cannot enable payment. Mandatory 3D Secure and exact-amount consent remain.
Security

Design

v4.9.144 · Protocol-correct package algorithms
Performance
No changes were recorded in this category.
Security
- Backup MX no longer probes mailbox existence before accepting incoming mail. Registered-domain and relay safeguards remain. Incoming flows distinguish domain validity, recipient probes in protected packages, content decisions, queue acceptance and actual destination delivery. SMTP AUTH appears only in the outgoing device flow. The package index and detailed diagrams now distinguish retry, permanent failure, quarantine and remote acceptance.
