This is a permanent error: No Such User Here

[Jonathan Balmant]

Hello,
I have sent emails through my account, and I have seen that some of these emails come back with the message listed below. There are all returning, a few. To seek better understand the problem, I sent for the same sender an email from a Hotmail account and it worked properly.
Could help me in any way?

Hello

Try searching the email address you sent to in /var/log/exim_mainlog to see the specific failure entry. EX:

exigrep [email protected] /var/log/exim_mainlog

Thank you.
