1. Go to the Application and user Management work center.
2. Select the view Email and fax queues
3. Here an email error SMTP error 552 5.3.4  is shown.

The SMTP error 552 5.3.4 indicates that the email you attempted to send was rejected because its total size exceeded the maximum limit allowed by the receiving mail server. In other words, the server refused your message because the email body + attachments (after encoding) were too large.

What the error means (in simple terms)

• Your email did not send because it was too large for the receiving server.
  
  
• This may appear as:
  • “552 5.3.4 Message size exceeds fixed limit”
  • “Message rejected. Size exceeds maximum permitted.”
    
    
• The rejection typically comes from the recipient’s server, not your own.
  
  

Common causes

• Large attachments (images, videos, PDFs, etc.)
• Multiple attachments whose combined size exceeds limits (especially after Base64 encoding, which can add ~33% overhead).
  
  
• Long email threads with accumulated attachments.
• Server‑specific size limits, such as Gmail’s 25 MB maximum.

1. Reduce attachment size
   • Compress files (ZIP/RAR).
   • Use lower‑resolution images.
