Re: Email to hotmail being rejected

You should really be asking the 3 (Mobile) Network this question. The IP address quoted is one of theirs and has been detected as a source of spam (not necessarily from your device – but any device using that IP). What do you think you were connected to when sending this email with a “From” address of “xxxxxx@virginmedia.com”? A free wi-fi hotspot – a “3HomeFi” or what?

I hope the above means Virginmedia. If not - who?

Your original post implied that YOU had sent the bounced message - because you didn't say otherwise.

If you didn't send the message - your address (but not necessarily your password) has been spoofed and fed into the email system via a 3 Network server by a spammer. Read this -

Re: Email to hotmail being rejected

Hi MJ459,

The failed delivery notification isn't spam. It is pretty much as BillC45 has advised and is related to the IP address you use when connected to your mobile network. Mobile networks use Carrier-grade NAT which permits the sharing of public IP's and therefore a previous user (of that IP) could have generated the spam trigger, as per the notification:

"Please be aware that if you are not sending mail from your own broadband connection that the listing may have been caused by a previous user ..."

Sending should work at some point when you re-try, or you could send whilst connected to your home network.

Hope this helps Smiley Happy
