Hi Team,

I am installed a newer version of CKAN on my RHEL 8.9 server. After configured all the services I noticed that everything work well except the mail notification, that are the last rows of log :

I use that configuration ( local postfix server ) in ckan.ini file : 

smtp.server = localhost
smtp.mail_from = "mail from"
error_email_from = "mail from"
#email_to = "mail to" 

Postfix works correctly and also the .ini file seems properly configured. I noticed a details regarding the .ini file; if the email_to is not commented causes the 500 error when I restart apache. There are no rules on firewall, ckan works correctly same for the postifix, I have tried several options including the use of an external mail server but still the error . Do you have any idea on how to manage this error ? 

Thanks in advance for your help.

Kind Regards,

Mattia
