I have a problem with check_email_delivery plugin.

When I I add a command in centreon and I trie (configuration\Commands) this all is a right. (A email is send from exchange to external, and the check email in external email box is good)

When I add this as a service, I have a critical error : EMAIL DELIVERY CRITICAL - plugin 1 failed: SMTP SEND CRITICAL - Could not send to [email protected]

I don't know why can you help me to resolve this ?

Thanks a lot and sorry for my bad english
