Hi @Karthik Kumar ,
whereas unable to send emails for other domains
Please have a check whether there is an internet Send connector in your environment.
If not ,you could refer to the following link to create it and then see if you can successfully send emails to external domains.
In addition, the Exchange 2010 is too old beyond support lifecycle, if you still want to use Exchange 2010, it is suggested to update Exchange 2010 to the lasted RU. But for a more secure environment and newer features, I would suggest you upgrade and migrate to Exchange 2016 (The latest version that can coexist with Exchange 2010).

Thank you for the information. I do have checked Send connector, rechecked all the MX, PTR, DKIM records all were configured correctly. From the last one month itself we are facing with this issue. Before that we had no problem in sending emails.
As you said to update Roll-up, I have updated also but, didn't getting the solution why the emails are unable to send to other domains. May I know, is there anything else need to be change?
Hi,
Do you receive any NDR reports when you fail to send an email? Did you check if they are stuck in the queue?
And please refer to following links to get the message tracking log for email that fail to send external :
Search Message Tracking Logs: Exchange 2010 Help | Microsoft Learn
Get-MessageTrackingLog (ExchangePowerShell) | Microsoft Learn
Get-MessageTrackingLog -MessageSubject “testmessage” -Sender “user@contoso.com”
If possible, please provide the complete screenshot about above imformation for our better research.

Hi,
It has been a few days and I am checking in to see how things are going on with this issue. Does this issue have any updates?
Hi,
I have posted 4 times of our issue. I don't know why it has not posted. Any how again I am posting here.
We are able to send emails to Yahoo but where as for Gmail unable to send. Throwed this following error.
mx.google.com gave this error:
[64.x.x.x x] Our system has detected that this message is likely suspicious due to the very low reputation of the sending domain. To best protect our users from spam, the message has been blocked. Please visit https://support.google.com/mail/answer/188131 for more information. v15-20020a056a00148f00b005415de7fd01si6709865pfu.203 - gsmtp

Try again. Make sure to enter your complete email address and your case-sensitive password.
If that doesn't work, then reset your email account password.
And if you're still getting this error message after a few or more failed login attempts, it's possible your IP has been temporarily blacklisted to stop what seems like suspicious activity. Wait two hours, and then try to log in again.
Once you're logged in, click Compose and send a test message to the same email address you're sending from. The sender and recipient should be the same.
After clicking Send, did you get a bounceback message? Check out Common Email Bouncebacks
Did the message fail to arrive at its destination?
If yes, wait five minutes, then check for new messages again. If it still hasn't arrived, check your email filters to make sure it wasn't moved to another folder. You may also check your spam or junk folder

Hi @Karthik Kumar ,
According to the error from google ,the reason you can't send mail to Gmail is that Gmail blacklisted your IP address and you should get off of the blacklist from the Gmail side to fix this issue.
Here's an article on how to get off of Gmail's blacklisted : https://www.rackaid.com/blog/gmail-blacklist-removal/
Hope it helps you a little!

Hi @Aholic Liang-MSFT ,
Eventhough, we have changed the IP address and checked in blacklist. The new IP is not in the blacklist but we are unable to send email to Gmail. It throwing an error same as previous " Our system has detected that this message is likely suspicious due to the very low reputation of the sending domain". Doesn't understanding where we stuck over.
