Email Issue - Quarantine, Safe Sender, or Whitelist Request

Use this when legitimate email is quarantined, repeatedly blocked, or needs safe-sender review.

Quick checks

• Confirm the sender address or sending domain.
• Confirm the message is business-related and expected.
• Check quarantine if you have access.
• Do not request broad domain allowlisting unless there is a clear business need.

Steps to try

1. Submit an Email Issue ticket and choose Quarantine / Safe Sender / Whitelist.
2. Include one example message with sender, recipient, subject, and sent time.
3. Explain whether this is a one-time release or ongoing sender relationship.
4. Wait for IT to review before trusting future messages.

Submit a ticket when

• Expected email is quarantined or blocked.
• A trusted sender is repeatedly filtered.
• A vendor/client email is missing and time-sensitive.
• You need review of a safe-sender or whitelist request.
