The blocking of outbound port 25 traffic is necessary to help curb the spread of viruses and spam from our network. Most customers should be unaffected by this measure. The following customers will be affected:

  • Residential customers sending mail through a 3rd party mail server with a mail client like Outlook, Outlook Express, Thunderbird or Mac Mail
  • Commercial customers not on a CCIP sending mail through a 3rd party mail server with a mail client like Outlook, Outlook Express, Thunderbird or Mac Mail
  • Customers that send mail through their company mail server and they do not use a VPN
  • Customers running their own mail server locally for outbound traffic.

Customers that will not be affected are:

  • Customers that use web based email like Hotmail, Yahoo mail or Gmail
  • Customers that use our mail server
  • Customers that have configured their mail client to use the message submission port (port 587) instead of the default port 25. The mail server that the customer uses will have to be configured to use this port.
  • Customers that send mail through their company mail server and they do use a VPN

If you are a customer that will be affected, These are some of the steps that you can take to minimize or remove the impact to you:

  • Use the webmail provided by your mail host
  • Change your outgoing mail port in your mail client to 587. Note: This only works if your mail server is configured for it. You may need to contact your email host.
  • Connect to your company network via a VPN
  • Contact us to setup a mail relay service for your domain.
