Exchange SMTP Authentication

[ITGURU]

I have a number of hardware/software devices which have the facility to send email notifications.

 

I have a situation where by when configuring these that the test emails will only send if I use my domain login and password.

If it change it to another domain user, I get an error saying the email failed and could not relay.

 

I cannot see why my account should be any different to any others?

 

For example we run PaperCut. For the email notifications it has to use my domain username and password as authentication, as if I change it to any other user or domain admin it doesn't work.

 

Running exchange 2013 if makes any difference but a bit stumped on this one as not aware you can restrict email sending by user, only host IP ?

On the receive connectors there's AD permissions if you don't have it set to anonymous, I'm guessing it's domain admin only by default? You'd have to add a service account/group to it

We setup a receive connector for each thing that needs to email anonymously and then use powershell to grant it anonymous rights (I could use the web gui I suppose but I don't). Usually from a specific IP and Port but just port if it's going to be lots of things.

 

If, for some reason, it needs to use authentication to send emails we just set up a service account for it.

All our 'infrastructure stuff' is on a seperate class C. There's a receive connector setup to allow anonymous smtp from this network range.

Check AD for the permissions as well. Make sure you can see advanced options. Select a user, Security, Advanced. Make sure (Include inheritable permissions from this objects parents) is ticked. Also, check your receive connector setup and make sure anonymous is selected.

 

Hope this helps.
