Hello all,

any update please?

Hello ​@adilbouazzaoui 

Are the emails actually received by the relay? It could be a network problem (centreon is not authorized, etc), or the name of the relay cannot be resolved by Centreon (DNS problem)… You can also check the relay logs.

Hi,

there is no network issue, the traffic is allowed, and when i run a test from the client i can see in our traffic monitoring that the relay received the smtp traffic from the client and that he forwarded it to microsoft

this is what i could find at the relay logs level:

it looks like the linux client is sending emails with some missed up alias or something?
 

Hi ​@cg-tw any update please?

Hello ​@adilbouazzaoui 

In your logs, root@/etc/mailname looks odd. It should be in the following format: user@domain_name.

Hello ​@cg-tw 

exactly. but i’m not sure how to fix it!

could you please show me how to get it fixed?

Thanks in advance

Hello ​@adilbouazzaoui,

I can’t really help you on that one, you alone know what the correct value is for the sender...

Hello ​@cg-tw 

yes i know, but i just need to you point me to the file where i need to change it.

Did you try what is in the documentation? https://docs.centreon.com/docs/administration/postfix/#step-2-configuring-the-credentials-of-the-account-that-will-send-emails

Hello ​@cg-tw 

i did the 1st time but it didn’t work, that’s why i’m using an SMTP relay on this client machine.

now to get this clear:

1- do i need to configure the credentials of the account that will send emails on client machine if i’m already using a relay?

2- if no, then how can i properly configure the client machine to use the smtp relay?

Maybe this can guide you
