Mail to live.co.uk bounce back

[GT60]

Hi I am trying to send an e mail to a  @live.co.uk address and it just bounces back.

Both e mails sent using my phone.

It worked when i used the TT Wifi and not data.

When i asked on the talk talk forum i was told this;

The originating IP address is the EE Mobile network.  So you're sending using mobile data. The sent message has a header that identifies the message with the tag email.android.com even though you're correctly sending via the TalkTalk outgoing SMTP servers. I'm assuming the tag email.android.com is being added by the email app on the 'phone.

The mail message is not being sent and there's an instant bounceback that references the microsoft servers. So, the implication is that microsoft is blocking the mail message.  But it's not clear that the reason for the block is because the EE Mobile network IP is blocked or the TalkTalk server IP is blocked.

The EE mobile IP address is on 4 blacklists.

The TalkTalk SMTP IP address is on 3 blacklists. (smtp.d-6.talktalk.net)

The TT email admins will no doubt have noted the d-6 fail and will have it in hand to identify the reason for the spam listing and put remediation in place to improve the reputation.

I suggest you see what happens when you switch off mobile data and use the Wi-Fi connection to your TalkTalk Home broadband router.

Thanks

It seems that your EE public IP addy has been blacklisted. All you can do is report it to CS & try rebooting your device until you get a new clean IP.
