Hi Ronni I have a mixture of IMAP and POP. I double tested Bigpond and "bouncing". I loaded another account, which is POP3 and sent it via Telstra 3G (sidenote: one day left on prepaid credit,..arrgghh what to do,..lol) and bounced it via iinet with SMTP Authentication to their servers. All worked fine. I then set up another POP3 account and played around with the settings on 3G for different servers and got them all to send too. :)
So not sure if that helps anything. :) lol The outgoing settings I have set up and turned on are:- mail.iinet.net.au with Password authentication and SSL Off, Port 25 mail.bigpond.com with no password authentication and SSL Off, Port 25 (but this is not active to use at all). The above are for the iPad on Telstra For Vodafone (which I also tested with a POP account) and bounced it via iinet through vf are pretty much the same. I have a few more set as "backup SMTP servers incase one fails" but 99% of the time, the first one works. ;) Hope that helps a bit. /shrug. (or is more confusing perhaps).
