What usually causes it
- The configured sender address contains a typo or invalid format.
- The mail server may require the From address to match or be allowed for the authenticated account.
- A saved sender/default address may have changed after a mail-system migration.
What to try
Check the device's sender address
Verify the full From address, including the domain, with the administrator responsible for the mail account.
Compare it with the SMTP account policy
Some mail systems only accept approved sender addresses for a given authenticated account.
Correct only the sender/mail setting
Do not reset unrelated network or printer settings when the server address and network are otherwise working.
Retry the same email scan
Send a small test to the same destination and confirm the mail server accepts it.
After each corrective action
Retry the same operation that produced SMTP 3007. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If 3007 returns with a syntactically correct address, the mail administrator should check sender/relay policy for the account used by the bizhub.
When service may be needed
This is an e-mail configuration condition. Do not bypass authentication or security controls to make the message disappear.
