My three Gmail inboxes have suddenly stopped accepting incoming mail. Each time a message is sent to any of them, Gmail throws an “authentication error,” yet the passwords for all three accounts have not been altered. I can still sign in and send messages without trouble, so the issue appears limited to receiving mail. I need a quick diagnostic and clean resolution so new messages flow in again and any queued mail is released. That includes checking account security settings, IMAP/POP configurations, filters, forwarding rules, and any server-side blocks that could be triggering the authentication warning. Deliverables: • Identify the root cause of the authentication error on all three accounts • Apply the proper fix or configuration change • Confirm that test emails reach each inbox successfully Please let me know your proposed approach and estimated turnaround time.

Hello, This looks like a delivery-break issue hiding behind a mail-authentication warning: since sending still works, the problem is likely tied to inbox-side access, routing rules, or a security/POP-IMAP restriction rather than the passwords themselves. I’ll inspect all three Gmail accounts methodically, verify security events, IMAP/POP state, filters, forwarding, delegates, and any server-side or client-side blocks that could be stopping inbound mail and leaving queued messages stuck. I’ve handled email security and account recovery issues across Gmail, IMAP/POP, and Linux-based mail setups, and I’ll use a clean diagnostic path so we fix the actual cause instead of just masking the symptom. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Would you like me to check whether these Gmail accounts are linked to any forwarding, delegation, or app-password setup that could be triggering the authentication error? I can start with a fast review and aim to confirm a working test delivery on all three inboxes within 1 day, depending on account access and whether any sender-side restrictions need coordination. Best regards, Asad

Hi! I can help you get those three Gmail inboxes receiving mail again. Since you can still sign in and send just fine, this is likely tied to app passwords, forwarding rules conflicting, or a recent Google security policy change blocking inbound authentication. I'd check each account's security settings, any connected apps, filters, and forwarding configs to pinpoint what's triggering the error. I'm Edward, 10+ years in email marketing and deliverability troubleshooting. This should be a quick fix once I can take a look. Let me know if you want to get started.
