SMTP Servers Closedown

SMTP Servers Closedown

We are in the process of closing down ALL outbound SMTP relay servers in a bid to reduce SPAM and issues of Blacklisting for all our customers. If you use these services you will need to make changes as below;

Q: I have my email with another supplier and wish to send out email from your Broadband

A: Use your email provider's servers with secure authentication for relay of email, any decent email provider should provide this facility. IC will not restrict you from sending SMTP via the network to your provider.

Q: I have a connection with you and an Exchange Server and want the SMTP smart host

A: All of our Office grade services provide the ability for INBOUND MX relay where we can act as a secondary mail relay host in case your server goes offline. For OUTBOUND email you should send this direct from your server and not via an intermediary please see these articles for how to set this up;

Exchange 2007-2010


Q: I have an email service with you and use a generic smtp server

A: All of our email services are now provided with a secure SMTP authenticated relay, you simply use the same inbound and outbound servers and same username / password details for both. You may just need to alter your settings for this to work. NB. If you are using mobile devices / more than one device accessing your email then you should take note of this related service announcement (click here).

NOTE: In order to send SMTP email direct then we recommend you have a valid reverse DNS entry setup and also on your domain name create a valid and restricted SPF key. This will limit and lock down your services to reduce the potential for errors. If you are unsure contact our support team for more details.
