Please try to create a new test mail account to send the mail,

if still get error, can I log in to your panel to check for you?

deydod

aaPanel_Jose I have similar problem.

I have uninstalled amavis and spamassassin services (due to high server load) however now all existing accounts can't send emails - they get this error. However if I create new accounts they work fine. Could you tell me what config files should I edit so can get the existing email accounts to work.
