I've had a few clients with Spark using @ihug.co.nz addresses with the old smtp.xtra.co.nz that's being shut off so I have attempted to move them to Vodafone's SMTP servers.
According to Vodafone's website, smtp.vodafone.co.nz is the preferred server. They say SSL access is available on 995 however trying that from either my Snap or the Spark connections results in no access.
I can access the regular smtp.vodafone.co.nz SMTP port from my Snap connection here, but of course Spark block 25 outgoing. Meaning these clients can't actually send emails after smtp.xtra.co.nz is killed off.
Here's the main bit: what SMTP server settings do I need that actually work for connections from outside VF's network?
Here's what I see from my Snap connection
$ telnet smtp.vodafone.co.nz 995
Trying 203.109.135.50...
telnet: connect to address 203.109.135.50: Connection refused
telnet: Unable to connect to remote host
$ telnet smtp.vodafone.co.nz 25
Trying 203.109.135.50...
Connected to smtp.vodafone.co.nz.
Escape character is '^]'.
220 cust.filter8.content.vf.net.nz ESMTP

And the same from a Spark connection
$ telnet smtp.vodafone.co.nz 995
Trying 203.109.135.50...
telnet: connect to address 203.109.135.50: Connection refused
telnet: Unable to connect to remote host
$ telnet smtp.vodafone.co.nz 25
Trying 203.109.135.50...
