I have a couple of mail accounts
.mac & work account through exchange, xtra is ISP.
.mac account - sends mail from iPhone using either 3G or wifi, whichever is available.
work account - sends mail from iPhone using wifi but fails when trying to use 3G network. Error is something about recipient email address being bad, which is crap b/c it works when using address and wifi, Strange!
smtp for work is smtp.xtra.co.nz (nothing special)
Strikes me as a VF back end issue? is that right?
Cheers
