My Asus Nexus tablet - had it since August 2012 - has the "option" to set up my home email client on it. My ISP is I discovered after set up that I could not send any emails using that client. Clear (Telstraclear) advised me after raising a query with them that they "block" my ability to send any emails because they do not wish to clog up their servers with spam. That is their policy with any android devices and there is no way around that.

Has anyone else run into this? I have a gmail account so can use my device to send emails anyway. Other mobile devices - non android driven - are acceptable for send and receive features of one's own email client.

Would the policy of Clear change now that Vodafone own them? Have I just by my own bad luck got the wrong ISP - depite that  have been with them all along (via Paradise then to Clear). Or should I have bought a device that is non android?

What comments and/or other experiences or advice have others got for me in this scenario?

Gradine:  So, in my travels I have to access my emails on my own email account via the Webmail route of the Clear website. That's cumbersome.

Just in case it wasn't clear, the reason you are having problems is to do with how your email client is set up on your android device.

When you connect to your ISP's SMTP server (smtp, without authentication, you can only access it if you are connected via a TelstraClear ISP connection - if you are accessing it through an Xtra or Vodafone connection, for example, it won't work.  This is by design and prevents people from accessing the SMTP server outside of your ISP's control (and is probably the explanation you were given regarding sending spam).

There are a few ways around this problem:
a) Enable SMTP authentication if your ISP supports it - usually this involves a different port and requires you to enter/save your username and password details for the SMTP server

b) Use Gmail's SMTP server to send your emails (but potentially replies will get directed to your gmail account from memory) :
Use authentication: Yes
Port for TLS/STARTTLS: 587
Port for SSL 465
password: password

c) Stop using ISP email, and migrate your email to gmail - you won't regret it, particularly if you ever want to switch ISP

Does anyone else think that sticking pins in ones eyes would probably be less painful than reading this thread?

Gradine: Oh Oh - Telstra Clera really does block android users from sending emails using the email client provided with devices such as (my) Nexus 7 and other mobiles.

 <content deletd>

Wonder whether TCL is the only ISP that places a block on the email client that comes with android devices?

Once again you've jumped to an incorrect conclusion. TelstraClear DO NOT block Android devices.

What you've described is the setup used by EVERY internet and email provider as a basic security measure.

There is no need to use Google (but you can if you want.) The solution to your problem is is much simpler and is answered by TelstraClear in the reply from them that you posted at the start of this thread. It requires you to set up SMTP AUTH to send using the TelstraClear SMTP server from any other ISP. Configuring SMTP AUTH is the best configuration option anyway as it allows you to send emails wheather you're connected to TelstraClear or any other ISP without making changes.

  • If you get an error 553 Relaying denied, then you have to check the outgoing email server address of the ISP your have access to. When you are connected to Clearnet, you have to enter the outgoing email server address of Clearnet, which is When you are connected to another ISP, then you have two options to solve this problem. Either you activate smtp authentication in your email program or you enter the outgoing email server address of the ISP you have access to. Check the support pages of the ISP you have access to for the outgoing email server address.
  • The ISP you are having access to is blocking port 25. If the ISP is blocking port 25, you may not be able to send email using your Clearnet account (even with smtp authentication). Some ISP's do this so that you are forced to use their email servers when sending email, as an attempt to prevent spammers to send spam through their emailservers.
