Daniel are you trying to send mail via xtra's mail server but with the from address set to something other than @xtra.co.nz?

eg

From: don@bowenvale.co.nz
To:  you
via:  smtp.xtra.co.nz

?

If that's the case, you can't iirc unless you've set up your xtra account with the domain.

So for me to do this I'd have to set up my yahoo xtra account to know that bowenvale.co.nz is a valid domain that I will be sending from.  You do that via their web interface and there are instructions to do it.

Personally I just don't. 

bowenvale.co.nz is hosted on mx.thinkdesignprint.co.nz so I use mx.thinkdesignprint.co.nz with my user name and password on port 587 to send my mail.

I use port 587 become some ISPs (and I think xtra is one) block access to external mail servers on port 25 (the default smtp port).

Hey all,

 

Is there anyone here who is an admin of the xtra mail servers for custom domains?

 

I simply want to know why an email being sent from an email server to xtras would get this showing up in SMTP logs of the sending server

 

210.54.141.1    [1224] 12:52:37 Client session <<< 553 Authentication is required to send mail as user@domain.com

 

I’m trying to go through normal spark support channels but they are trying to ask me questions about the email server I administer which are ridiculous and very frustrating.

 

I’m fairly sure (with my knowledge of SMTP) the issue is that our server is saying its sending an email from an email account that is hosted on xtra servers and trying to send to the same email/account without first specifying auth

 

I have given them more than enough information about the issue already and just not getting anywhere.
