[Web-cyradm] Undeliverable mail errors

[Stephen K Cheboi]

Hi,

I have followed the postfix-cyrus-web-cyradm-HOWTO documentation.

Configured my system to relay mail via an existing e-mail server also using
postfix, I can send mail outside, but when I try sendmail back to my new
e-mail server after creating an alias which should forward mail to a created
account, I get the following postfix error.

How can I fix this? I have tried to read widely, but haven't achieved much.

 

 

This is the Postfix program at host kenkob.kenkob.co.ke.

 

I'm sorry to have to inform you that your message could not be be delivered
