[tomsmi]

Hi, if my smtp server requires authentication but presents itself with self signed one, how can i import this certificate to be trusetd by Veeam Agent for Windows?
Part of Svc.VeeamEndpointBackup when trying to send test e-mail:

Hello and welcome Tomasz,

Try to install your certificate on local machine like described in this article - Managing trusted root certificates for a local computer and let me know how it goes. Thanks.

Thank you Dima, It really worked well!

But there is another thing that is not clear for me now.
I am able to send mail only if I enter credentials of a user that is able send and receive e-mail in my e-mail server. And this must be the same user.

So, this setting works:



But this settings results in errors on e-mail server:


Errors:

I'd like to have situation that I can have one service e-mail account in company for e-mail notifications, and those e-mails could be received by another user (for example: every owner of workstation or server can receive e-mail about backup of his own machine).

Hi Tomasz,

That true. VAW allows to use a single FROM/TO email address. You set different From and To address via API like described here

Hi Dima, thank you for explanation.
