How very odd

Titan!

When I'm on the wifi network at home I can't successfully send emails from the iPhone: I get an error that the address I'm sending to is being rejected by the server. Turn the wifi off and the email gets sent immediately.

But that's the only Internet service that doesn't work on wifi on the iPhone. Receiving emails, twitter, web: all OK.

And apparently posts to LJ twice.

Apparently so. I've deleted the duplicate.

I could argue that the LJ app also works but is perhaps just a touch enthusiastic. :)

It's likely* to be the outgoing SMTP server on your email account that's the issue.

While on the wireless it will try to route the email out through your ISPs outgoing SMTP and fail miserably.

* Likely as in "not definitely but I've seen this behavior more than a few times before"

That does seem to be the consensus. Still not sure what I can do about it... the available settings on the phone are less than obvious.

If you go into:
Settings -> Mail, Contacts, Calendar -> Accounts -> YOUR MAIL ACCOUNT -> Account -> Then on mine it's called "Outgoing Mail Server" on one and not there on the other so... Maybe the first one? -> Add Server -> Whatever the details are for your ISPs SMTP server -> Profit!

That looks like it should work I think.

Thanks, I'll give that a try.

I assume that your email is using smtp from telstra or some other isp in Australia. The issue is that your mail server does not recognise your home wifi connection as within its own network and then assumes that someone is trying to send spam.

There are some work arounds available... I think the responses to this link list a few:

Yeah, pretty much that. Your mail server doesn't allow relaying, because few mail servers allow relaying from a network that they don't recognise, because that way lies spam and we all hate spam.

That workaround on the link Fogod provided there is a very convuted workaround. The simplest way is to authenticate with your SMTP (sending mail) server before you send, if you mail server allows it. Change your sending mail server setting to allow sender authentication with password, if you haven't already. You probably also need to change it so it is using a secure port via SSL. This might not work unless your outgoing SMTP server is the same as your email provider etc (ie if you have, say, iinet email, better not to use Telstra as your smtp server).

If there is one thing I have very much learnt from my years of sysadmining, it is that email is *vastly* more complicated than most people think, far more so than most other services. THis is partly due to various exciting egregiously bad designs in early email standards, including the bright idea that the default way for email servers to work was with no authentication at all.

Thanks for that.

I think I've found the settings for that and I'll give it a try.

Part of the oddness though is that email through the wifi on the laptop works just fine.

The other workaround I've discovered is (and much simpler than the one in the link: switch wifi off, send email, switch wifi on. :)
