Problems with mail relay through relay1.vodamail.co.za

[MadMailMan]

Hope somebody can help me here. I have a client who is having problems getting email from somebody using the vodacom network. The message the senders is getting back says ...


This is the Postfix program at host relay1.vodamail.co.za.

Now this [email protected] points to a vodacom server and not my MX's. Any idea what they are doing and how to fix it?

It looks like Vodacom have not added that domain in their Postfix config >
mydestination = interactivecapital.co.za

It shouldn't be in their destinations. It should just send the email to my server on the IS backbone. I have the authoritative DNS for the domain and popper.inter... doesn't (and shouldn't) even exist. Does Vodascum not know how email works?

I constantly have problems sending mail out via my vodacom 3G card as vodacom mail servers are always blacklisted in dnsbl's (I have now resorted to routing via gmail when on 3G). So yeah, they don't have a clue how to manage mail servers.

Which SMTP server do you use?

v3g I don't know which smtp server the guys are using but they are blaming my client (i.e me) but you can clearly see that it's relay1.vodamail.co.za that can't deliver the email. And what DNS setup is vodacom using? Because it's not picking up my authoritative! Where is vodacom getting popper.interact.... ????
