Gmail email login

551 generally is the email server telling you outgoing mail needs authentication. Contact your email provider (internet provider, Gmail, etc.) or look on their website for how your SMTP configuration needs to be set up in your email client.

Maybe, try setting-up a second Gmail account, then send transfer) your emails from the old username account to the new username account. If this works, then either try deleting the messages from the old gmail account and transfer the messages from the new gmail account back to the original gmail account ... or ... just delete the old gmail account if you successfully transferred them to the new gmail account.

Standard instructions for email inbox setup:

i have finished my corby pro email settings & i can send and recieve emails. the problem with only recieving & not able to send is the confusion between port numbers. in secure connection box three options available ' off ', ' SSL ', ' TLS '. use only SSL or TLS because the port numbers for SSL & TLS differs. just try this & you will be able to send and recieve emails.

                                                    SMTP port - 465

                                                    POP3 port - 995

Enable POP in Gmail. Don't forget to click Save Changes when you're done.Configure your client to match the settings below:Incoming Mail (POP3) Server - requires SSL:pop.gmail.com
Use SSL: Yes
Port: 995Outgoing Mail (SMTP) Server - requires TLS or SSL:smtp.gmail.com (use authentication)
Use Authentication: Yes
Port for TLS/STARTTLS: 587
Port for SSL: 465Account Name:your full email address (including @gmail.com or@your_domain.com)Email Address:your email address ([email protected] orusername@your_domain.com)Password:your Gmail password

Unless you're using recent mode to download mail to multiple clients, make sure you've opted not to leave messages on the server. Your Gmail settings determine whether or not messages stay on the server, so this setting in your client won't affect how Gmail handles your mail.

Please note that if your client does not support SMTP authentication, you won't be able to send mail through your client using your Gmail address.

Also, if you're having trouble sending mail but you've confirmed that encyrption is active for SMTP in your mail client, try to configure your SMTP server on a different port: 465 or 587.

You're now ready to use POP with your Gmail address.

Typically this error indicates that you are trying to send your Adhost email through Adhost’s mail server when you have not authenticated your email account to send mail. Our mail server authenticates you through your pop account. So when you check your email, our mail server authenticates your pop user and password, captures that IP that you are checking your email from, and adds that IP to our relay list. This list is flushed every 70 minutes. This means, if you try to send email after the relay list has been flushed and before you’ve attempted to check your email, you will receive this error.


How to fix the problem:

Fix #1 - reauthenticate on our server.

Remove any email from your Outbox. If you need to keep the message, you can move it to your 'Drafts' folder.
Click "Send/Receive". This will reauthenticate you.
Try resending the email.
Fix #2 - configure your email client to check for email before sending.

In Outlook, go to "Tools" and select "Email Accounts". Make sure "View or change existing e-mail accounts" is checked. Click Next.
Select your account from the list and click "Change".
Select "More Settings".
Select "Outgoing Server".
Check "My outgoing server (SMTP) requires authentication".
Select "Log on to incoming mail server before sending mail".
Click "OK", then "Next", then "Finish".

This will fix your problem
