In this case I would just drop the vanity NS. There is no good reason to have them really. It's likely you are the ONLY person that ever sees them. If you are actually using your own servers then thats another matter; but as you said it's just for appearance sake.

Support told me to leave ovh's dns servers for the SOA and NS records but keep my vanity nameservers as the domain's DNS servers. The email aliases are working now but I'm still using the vanity NS. So I think it's fine like this...

No I created my DNS Servers using the Glue Registry in the manager so I am actually using OVH's DNS servers

Are you hosting the DNS yourself? If so, could you not also host mail yourself?

Any ideas?

Hello
I have a domain with ovh, without hosting, and I created two email aliases for that domain.
However if I send an email to any of the email alias I get this error:

host redirect.ovh.net[213.186.33.5] said:
553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1) (in reply to RCPT TO command)

The MX record is

mydomain.com. IN MX 1 redirect.ovh.net.

It must be said that I have created custom vanity DNS nameservers for that domain (and everything else is working fine, only the email aliases aren't working!)
so my SOA and NS record have been changed like this

@ IN SOA    ns1.mydomain.com. tech.ovh.net. (2015012001 86400 3600 3600000 300)
  IN NS     ns1.mydomain.com.
  IN NS     ns2.mydomain.com.

And if I change the zone file back to the original records apparently the email aliases work! (SOA dns110.ovh.net and NS dns110.ovh.net and ns110.ovh.net)

So is there a way so that I can use my vanity nameservers and the email aliases work?
