Blocking Spam and Unwanted Emails

Keep your inbox clean by blocking spam senders and managing unwanted emails.

How Email Blocking Works

SDesk automatically filters emails and can block senders. Blocked emails:

• Don't create tickets
• Don't trigger notifications
• Are stored for review (can be recovered)

Automatic Blocking

SDesk automatically blocks emails that fail security checks:

• SPF Fail - Sender's IP not authorized to send from that domain
• DKIM Fail - Email signature doesn't match
• DMARC Fail - Domain policy violation
• Virus Detected - Malware found in attachments
• Spam Score - High spam probability

Manually Blocking a Sender

1. Go to Settings → Blocked Senders
2. Click Block Sender
3. Enter the email address or domain to block
4. Add a reason (optional but helpful)
5. Click Block

Blocking from a Ticket

1. Open the ticket from the unwanted sender
2. Click the menu (three dots) in the ticket header
3. Select Block Sender
4. Confirm the block

Block by Domain

To block all emails from a domain:

• Enter @spammydomain.com when blocking
• All emails from that domain will be blocked

Viewing Blocked Senders

1. Go to Settings → Blocked Senders
2. See all blocked addresses and domains
3. View the block reason and date
4. See how many emails were blocked from each sender

Unblocking a Sender

1. Find the sender in your blocked list
2. Click Unblock
3. Future emails from this sender will create tickets again

Recovering Blocked Tickets

If a legitimate email was accidentally blocked:

1. Go to Settings → Blocked Senders
2. Find blocked tickets from that sender
3. Click Restore to create a ticket from the blocked email
4. Consider unblocking the sender

Best Practices

• Review your blocked list periodically
• Block domains rather than individual addresses for persistent spammers
• Add notes when blocking to remember why
• Check blocked emails occasionally for false positives
