Hmmz.. that could mean several things.

It could be related to this:

You really have to dig into your mail logs to see what's wrong.
/var/log/exim/mainlog
/var/log/exim/rejectlog

Next to that, check if your server settings are all correct, go to https://www.mail-tester.com/ and test your mailserver.
If you don't get a 10/10 then you will have issues, they will be explained in the result page.

Is that all? Hmmz... what is the result of the mail-tester.com test?
Sender verify failed could also point to something missing in SPF and/or DKIM record.

I can see a lot of log reports. I tried to send an email from my other servers. That's why I post it. Richard I tried to check with the mail tester. Its says "Please send your message to a [email protected]-tester.com address "

Any idea about that ?
 
Yes that is correct. You visit the mail-tester.com page and you will get a unique code to send an email to.
It's something indeed like [email protected]-tester.com and you send just some testmail to there but do NOT close the browser page.
Now wait a minute until your email is processed, then press the "check your score" button below it.

You will get a score then and a report about what is wrong and can be improved.
Since you wrote only some clients of you have issues, I presumed your own email at the server is working. This should be send from a working email from the server to the mail-tester.com address given on the site.

You can also send me your domain name per pm if you don't want to post it publicly, I can have a look if I can discover anything.
But still I would start with the mail-tester.com site if I were you.
