Hello,

From logs I see a delivery from [email protected] to [email protected] and to [email protected] fails.

nslookup tells:

Code: 
ricolou.eu: Non-existent domain

and whois show the domain is not registered.

Exim by default is configured to verify sender with line:

Code: 
require verify = sender

in /etc/exim.conf

That's the possible reason.

Thank you for the reply. Now i realised whats could be the problem.

I already turned off the #require verify = sender line but still got the message.

I want to send email from [email protected] to [email protected] (my company email) but i got this message. I use cloudflare and yandex mail. Not undertand why i got this.

BUT.

I got one question. How to turn off at exim.conf to never check the recipient address is exist or not?! Seems the system give false checks and many customers got this problem. They could send emails to any providers (@yahoo,@yandex,@gmail etc.) but for custom domains not really.
