Re: iPhone sending email on telstra

[Paul van der Mey]

Hi Alex

I'm on 3G with Telstra.
My ISP and e-mail account are with TPG.

Initially had no joy sending e-mail via the iPhone when on 3G.

I used my e-mail account set-up in Mail to test the settings I needed based on 
what TPG said I would need, including alternate Ports.

Found that my user name required the full e-mail (@tpg.com.au) to work with 
SSL turned on.
When I got it working I then transferred the details to the iPhone and it 
worked.

Using authentication also allowed my wife to send e-mail from her MacBook when 
connected to the internet at her work. Without the SSL/Authentication she could 
not send e-mail when connected to the internet at her work.

The connection I make is that when connected at home via ADSL TPG knows that 
authentication is not required because of the physical link / direct connection 
to my ISP. When attempting to e-mail from another location on the internet 
(indirect connection to my ISP by IP address or 3G) the access is blocked by 
TPG in an attempt to stop unauthorised use of my e-mail account. So for me it 
was not a Telstra/3G issue in any way, shape or form. My ISP provided enough 
information by using my log-in details and information in their help pages to 
sort this out (server/host name, alternate port numbers).

Also have:
 - the TPG outgoing server set as the primary SMTP server
 - SSL turned on for incoming messages (Settings -> Mail, Contacts, Calendars 
-> Accounts  -> Advanced -> Incoming Settings )

Thank you

Hi all,

Thanks for all your help and great information. I am also using SMTP 
authentication on port 25 with TSL/SSL on, but I am not able to send any 
messages neither from my iPad nor my iPhone. Both these are connected to 
telstra. Happy to hear that VF has the same issue so I won't try them. Also 
both these are on pay as you go. If I had to be "business packages" these might

I wil also try to speak to my local telstra dealer just to hear what they have

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

Hope that helps a bit. /shrug. (or is more confusing perhaps).

 I don't agree with your comment that blocking port 25 does nothing to
 reduce
 spam.
 
 Mail servers communicate with other mail servers using port 25. Allowing
 unrestricted access to external servers through port 25 just permits
 infected
 PC¹s to pretend they are mail servers, sending mail directly to any other
 mail server on the Internet without having to have email access,
 authentication or privileges on any legitimate system.
 
 ISP blocking of port 25/465 cripples the existing zombie botnets, leaving
 them unable to spam, but has no effect whatsoever on mail server to mail
 server traffic.
 
 Port 25 Blocking disrupts viruses and malware programs that get on ISP
 customer machines and send out spam emails.
 The emails must now be sent through the ISP's mail server so they can
 monitor
 the volume of email and control spam sent through their systems.
 
 While blocking Port 25/465 won¹t end spam, it does make it much more
 difficult for spammers to send the volume of email they do using infected
 PCs.
 
 It will also have the effect of sparing a lot

Re: iPhone sending email on telstra

[Pete Smith]

G'day all.

Just my 2 bob's worth. I was reading this thread and decided to try my iPhone. 
I haven't had any troubles before, although I hardly use the email on the 
iPhone. I'm with Internode as my ISP and Telstra on the phone plan. I have two 
email accounts on my iPhone, this main one and another specifically set up to 
use just on the iPhone.

I disconnected from wireless and made sure I was on 3G and then sent one email 
from each account. No problems. Both flew away with a whoosh.

My main account (this one) is set as a POP account and the other is set as IMAP.

Now here is the interesting thing. When I was setting up the iPhone email 
account (which was not long ago and quite some time after the original) I was 
having all sorts of dramas as I just assumed that as my original account is a 
POP, so would the new one. Finally, I rang up Internode who were (and have 
always been) extremely helpful. The bloke on the other end said it was an IMAP 
not a POP account. When I asked why it wasn't the same as my other account he 
replied that even though it says it's a POP, it is actually an IMAP. Internode 
only have IMAP!! 

So: Apparently, I have one POP account and one IMAP account on my iPhone but as 
far as Internode is concerned, they are both IMAPs.

I don't know how that works but do I really care? No way. They both send and 
receive emails on Telstra 3G with no probs and that makes me happy.

Have good day. I'm heading back to my Phantom collection on Bento!

Re: iPhone sending email on telstra

[Rob Findlay]

Anyone can get a free Gmail account. In your Gmail settings you can setup your 
main account as the address to send email from. This means Gmail will send mail 
for you with the return address of your own preferred email account.

Once this is setup you can use smtp.gmail.com with SSL on port 587 as your 
primary outgoing server and it pretty much works anywhere on any device.
If you have a SPAM problem you can also forward your mail to Gmail to run it 
through their amazingly effective filters and store it in IMAP  form on the 
server in practically unlimited quantity so you never risk losing mail if your 
computer crashes.

Good Value.

Re: iPhone sending email on telstra

[Ronda Brown]

Hi Daniel & Alex,

Daniel, are all your email accounts IMAP? Or can you send using a POP account 
on 3G Network?

Like Susan mentioned in her reply, when on the 3G Network I have to use my 
MobileMe IMAP Mail account to send (which is what I do).
As I cannot send using my Westnet POP Mail Account, unless I change the 
Outgoing Mail Server (SMTP) to mail.bigpond.com.

Both Westnet & MobileMe 'Outgoing Mail Server (SMTP) use Default Ports 
25,465,587.
Westnet SMTP is: Authentication NONE & does NOT use SSL (Secure Sockets Layer))
MobileMe SMTP is: Authentication Password, Username & Password & does NOT use 
SSL (Secure Sockets Layer)

I have my MobileMe ro...@mac.com set as my 'Default' Primary Account on my 
iPhone, so all mail is sent via ro...@mac.com. 
I have the same issue when travelling with my MacBook Pro and connecting 
through other Networks in Hotels.
I can send using my MobileMe Mail account, but not my Westnet Mail Account 
unless I change the server.

I can see where Alex is coming from, but as I use my MobileMe account as 
default primary account, it doesn't really trouble me that much.

Cheers,
Ronni

Hi Alex

Not sure if you saw my post, but I mentioned that I've managed to send
emails out while on the Telstra network via my iPad and the only outgoing
server I use with it is iinet with Authentication. (which is my home ISP)
I also mentioned I use my iPhone with 4 different outgoing SMTP servers and
they all work and I never have email held or stuck.

Re: iPhone sending email on telstra

Hi Ronni,

If this measure is to prevent infected PC from pretending they are mail servers 
it will definitely not work. Why would a spammer route their traffic through 
the invested user's ISP default mail gateway. They would simply delivery it 
directly to the intended final destination. The same goes for spammers. They 
would simply setup their own mail server. What they would not do, is use a 3G 
service provider for this as wireless data is simply too expensive. So as far 
this measure only prevents me from send email via my own mail server while 
connected to my ISP's network. Also in some cases upgrading to what they call 
business packages does not offer this "feature"

As seems to be the case it doesn't even require any form of authentication nor

There are also other implications of sending your email via a third party mail

Ronnie, how did you configure you mobile to send via Mobile Me. Via the

Hi Alex,

I don't agree with your comment that blocking port 25 does nothing to reduce 
spam.

Mail servers communicate with other mail servers using port 25. Allowing 
unrestricted access to external servers through port 25 just permits infected 
PC’s to pretend they are mail servers, sending mail directly to any other mail 
server on the Internet without having to have email access, authentication or 
privileges on any legitimate system.

ISP blocking of port 25/465 cripples the existing zombie botnets, leaving them 
unable to spam, but has no effect whatsoever on mail server to mail server 
traffic.

Port 25 Blocking disrupts viruses and malware programs that get on ISP customer 
machines and send out spam emails. 
The emails must now be sent through the ISP's mail server so they can monitor 
the volume of email and control spam sent through their systems.

While blocking Port 25/465 won’t end spam, it does make it much more difficult 
for spammers to send the volume of email they do using infected PCs.

It will also have the effect of sparing a lot of small business from having 
their mail servers relentlessly pounded to the point of crawling or crashing 
altogether.

Almost any current email client can send outbound mail through the mail server 
of your choice using port 587. 
This being the actual port, as specified by RFC 4409 for such client submission.

Again I mention: Most, if not all internet service providers block the use of 
SMTP servers that are outside of their network or not provided by the ISP being 
used for your internet connection at the time unless the SMTP server is 
authenticated. This restriction is part of an overall effort to prevent spam 
emanating from the ISP's domain and when connected to a cellular internet 
network for internet access is no exception. 

This has been in place and an issue for a long time - well before the iPhone, 
iPod Touch, and iPad were introduced that firmware update 4.0 can't do anything 
about. 

> 
> Are there any 3G service providers which do not do this ?

Most ISPs don't provide an authenticated SMTP server, but a number of other 
email account providers do. 
Apple does with a MobileMe account, and so does Google with a Gmail account to 
name only two. 

I use my MobileMe Account to send from when on Telstra's 3G Network.

Re: iPhone sending email on telstra

[Alexander Hartner]

Hi Ronda,

The problem is that blocking port 25 does nothing to reduce spam, and 
realistically what spammer uses their mobile?

The problem with forcing users to set an alternate SMTP server is that it break 
SPF (http://en.wikipedia.org/wiki/Sender_Policy_Framework) which does a much 
better job at reducing spam. With SPF each domain specified a server which is 
the designated mail server for that domain. On the receiving end when a message 
is received, the receiving server can then check via the public DNS record 
whether the message originated from the authorised server. This ensures that 
the email came from it's proper origin. Most domain owners would take their own 
precaution to prevent anyone form using their mail server to distribute spam, 
or they will find themselves being blacklisted very quickly. 

What telstra and bigpond allow all their clients to send emails with the sender 
having the option to choose just about any sender address. This is typically 
considered very poor form, as it would allow me for example to send a message 
which to most users would look like it came from somebody else. The technical 
term for this is an "open relay" and is a real problem.

I guess this has been a problem for some time and will be not addressed any 
time soon. 

Are there any 3G service providers which do not do this ?

Re: iPhone sending email on telstra

[Susan Hastings]

Hi Alex, Because I've used different providers at home and at work, plus on 
mobile phones, I've always taken it for granted that using POP email means I 
have to change the outgoing server address for suit the current ISP. On my 
iPhone its Telstra, but when I used a 3 phone I had to use their outgoing 
server as well. I don't know what the current situation is, but it makes sense 
to me to have to change the outgoing server depending on the network, even 
though the incoming mail always comes from iinet.

Of course, my mobile me account is IMAP, so a different story.

And iinet also allow me to to set up an IMAP account, so if it bothered me, I 
would do that instead of POP.

cheers, Susan.

Re: iPhone sending email on telstra

[Daniel Kerr]

I must admit, I've never had a problem with this.
I created about 5 outgoing SMTP Settings.
My iPhone is the 3Gs version. I am with Vodafone with the phone and iinet
ADSL at home.
As mentioned I have about 5 outgoing servers.
These are:-
€ the Vodafone SMTP setting
€ iinet's SMTP setting (no password)
€ iinet's SMTP setting (with username and password)
 and 2 other of my own server settings (with and without authentication)

And I've found emails send out on the road and from home with no adjust at
all. They always go (one way or the other), and I never have to turn any
settings off.

I also do the same with the iPad. Though it's with Telstra for the SIM while
I tested it in the country in the middle of nowhere (which worked extremely
well by the way). With the iPad I just have the one smtp setting, which is
iinet's setting with authentication. It works perfectly every time.
So I never use the mail.bigpond.com at all.


Another option for travels, if they are having a lot of problems with SMTP
servers etc is the following. It's not free, but it's month by month, so you
can just pay for what you want to use.
It's 
You sign up for it, costs about $2-$4 for the month. And you use their smtp
settings/server to "bounce" mail. Never have to change or adjust or find out
settings. It just works.
Have a few clients that travel a lot, and they've used it a few times where
hotels or settings have played up, and they need email to go quickly. Signed
up for it for the month away and no problems at all. Then just lapsed it
when back.
Of course, it's not a "perfect option", but then sometimes nothing ever is,
and its what works at the time. ;o)

Hope all that helps.

Kind Regards
Daniel

Re: iPhone sending email on telstra

[Peter Meyer]

Yes but it's not just a Port 25 issue and the phone _should_ try the various 
SMTP settings in succession until it finds one that works; not necessarily the 
Primary SMTP server you have designated (see the Settings>Email>Outgoing Mail 
Server on your phone). 
But it never has for me (I started a thread about this almost 2 years ago, in 
fact)
 
So if I want to send email via 3G it's necessary to manually turn off my ISP's 
SMTP setting (The Primary server); the Bigpond setting then does the job as it 
should.
And that's persisted through several OS upgrades.

Re: iPhone sending email on telstra

[Ronda Brown]

Hi Alex,

You will find most/many ISPs block what is called "Port 25" which is the port 
used to send e-mail. 
They are doing this to cut down on the amount of spam that is sent from their 
networks.

All e-mail sent via the Internet is routed through the port 25, the channel 
used for communication between an e-mail client and an e-mail server. 
Even though port 25 blocking will probably become an industry standard, 
however, the filter can create problems for e-mail servers and block legitimate 
e-mail as well as spam.

Port 25 blocking allows ISPs to block spam sent out through their networks, but 
it tends to punish the innocent that have a need to send through e-mail servers 
other than those belonging to their ISP. The ISPs that block port 25 require 
their SMTP server to be used instead of the remote SMTP server or a SMTP server 
running on your computer.

Cheers,
Ronni

Hi Susan,

Thanks for the help. I had a look online and indeed this is the case.

Personally I find this rather shameless as well as outright dangerous.

How are the other providers (Vodafone, Optus etc) dealing with this ?

Your outgoing server needs to be mail.bigpond.com to send emails from pop 
accounts.
