Gmail delivery response

Gmail 552 5.2.2: The recipient's inbox is out of storage space and inactive

The recipient's Google account has no storage available, so Gmail cannot accept the message. The recipient must free space or increase storage.

Problem description

A representative response is:

552 5.2.2 The recipient's inbox is out of storage space and inactive.
Is this temporary or permanent?

Treat this as permanent until the complete provider response and retry behavior show otherwise.

How to resolve it

  1. Confirm the recipient address is correct.
  2. Ask the recipient to free Google account storage or increase its storage plan.
  3. Wait until the recipient confirms the inbox is active.
  4. Send the message again once.

MailFixIt scope

This is a recipient storage problem, not a sender DNS problem. MailFixIt cannot change the recipient’s account storage.

The recipient’s Google account is out of storage space and cannot receive the message.

Can MailFixIt prove this entire bounce from public DNS?
