SPF record for smtp.vodamail.co.za?

[BarnettE]

I would like to set up an SPF record for my domain. I sometimes use smtp.vodamail.co.za for my outgoing email. Does anyone know what is the correct way of specifying the outgoing mail servers for Vodacom? It looks like it should be something like:

a:relay1.vodamail.co.za
a:relay2.vodamail.co.za
a:relay3.vodamail.co.za
a:relay4.vodamail.co.za
​

Is there a better way of doing this? Like Google who has a single

include:aspmx.googlemail.com​

that one can use?

Thanks

This is how mine are setup:

domain.co.za. IN TXT "v=spf1 ip4:196.XX.XX.0/27 ip4:196.211.XX.XX ip4:196.25.XX.XX ip4:196.35.XX.XXX ip4:196.35.X.XX ip4:196.35.X.X ip4:196.26.XX.XXX ip4:196.26.XXX.XXX a:smtp.dial-up.net a:smtp.isdsl.net a:smtp.saix.net a:smtp.dsl.telkomsa.net include:saix.net ~all"

XX`s for security reasons.

AFAIK with Vodacom you will have to specify each relay server... and they change them, and their IPs from time to time.

Hi w1z4rd,

If I understand you correctly, you recommend using a larger IP block:
Considering the IPs for the 4 servers they currently have are:

relay1.vodamail.co.za -> 196.11.146.226
relay2.vodamail.co.za -> 196.11.146.227
relay3.vodamail.co.za -> 196.11.146.165
relay4.vodamail.co.za -> 196.11.146.166
​

So using

ip4:196.11.146.0/24​

instead will ensure that the SPF record remains valid even if they add more servers - assuming of course they stay within the 0-255 block...

OK, this is the SPF record I went for:

v=spf1 a:relay1.vodamail.co.za/24 include:aspmx.googlemail.com ~all​

This is to allow email to be sent via either smtp.vodamail.co.za or smtp.gmail.com. So far it seems to work fine. Unless of course someone can come up with something better. I don't like the idea of having to guess what will work now and in future. I would have preferred something more official - something that Vodacom will ensure remains valid in future.
