Why are my emails not being forwarded?

Most mail sent through the 123-reg Mail Servers is forwarded to other email providers such as Gmail and Hotmail. As this is a shared service, there are a few external factors that can impact of the server’s performance.

As this is a shared service, performance may be limited by the actions of other users. For example, rouge users could cause a build-up of backlogged mail, and can even cause the server to become blacklisted.

There is also the possibility that some users may be using the system to spend spam and other malicious email. In this case, other email systems my see this spam and blacklist the server.

This could cause your emails to be delayed or, in the worst case, bounced back.

MX Server Bounce backs

A MX record is a type of DNS record which is responsible for accepting incoming email and routing it to a specified mail server, based on the information in the record. 

One special feature is priority numbers, which provide information to the querying mail server about which mail server should be used first. The next entry is tried only when the mail server with the highest priority is not available. The priority of priority numbers rises in opposition to the value of the number, meaning that lower numbers have a higher priority.

Another special feature is that only domains may be entered for mail servers. An entry referencing an IP results in an error.

123-reg's servers are configured to check to see if email is coming from a Smart Host server, this means that we check that the server we are receiving the email from is authenticated to send email as coming from that domain.

For example: If you were to send an email from user@ISP-Provider-UK.com through the SMTP server mail.ISP-Provider-UK.com, to a domain using our servers we will check if user@ISP-Provider-UK.com is authorised to send through mail.ISP-Provider-UK.com. If the domain is authorised to send through the server we will accept the email, if however the email hasn't gone through a Smart Host server and came from an Open Relay server we will block the email, as this method is widely used by Spammers.
