Spamhaus IP blocking

Hi,

 

I changed the password on a email account (provided by 123-reg) and now the outgoing emails are being blocked. Incoming is fine. I have followed links and the following appeared. How do I unblock? Thanks.

Hi. Welcome to the forums.

 

It looks like there is a setup issue when you use the 123-reg email account. How are you sending emails ? Is it via 123-reg mail servers (or your own) ?

 

The system is seeing your public IP address, and rightly is on the blocklist as users should be using either the ISP (in this case BTinternet smart host - mail.btinternet.com), or your own mail server or other company mail server. However for the latter, it typically needs to be correctly setup with the IP address of that company and have a correct rDNS.

Re: Spamhaus IP blocking

@Andy_N I've seen this before where the end user's IP address is shown as the sending address rather than the SMTP server, but I can't remember how it was resolved.

 

@bridgfordkid@If you have an @btinternet.com address, you could send using mail.btinternet.com SMTP server authenticating with your @btinternet.com addres and password.

I too have been racking my braincell why the end user's IP address is being treated as the sending IP address rather than the mail server one. It might be to do with SPF or rDNS, but the OP just changed a password !

 

Perhaps a support ticket to 123-reg might be an idea.
