Problems sending email when travelling or abroad
Posted by Helpdesk Admin on 01 February 2010 11:48 AM

Sometimes when using a wifi hotspot or mobile broadband when travelling, you may find that you cannot connect to our mail server (errors are displayed) and you cannot send email messages. When you return home, everything is fine again.

This is because many hotspot and broadband providers prevent you sending outbound emails on port 25 to any servers except their own designated email relay machine. This is to prevent their IP addresses getting blacklisted by virus or trojan infected machines that are using their network. The side-effect is that legitimate outbound emails are also blocked.

To allow you to work around this, our mail server will also accept authenticated email connections on port 587. You should change the port number for SMTP outbound email from 25 to 587 in your email program before you travel (this setting will also work at home so you can leave it that way).

To do this in Microsoft Outlook:

  • Click Tools -> Email Accounts
  • Click 'View or change existing accounts'
  • Select the email account you wish to modify and click 'Change'
  • Click 'More Settings' and select the 'Advanced' tab
  • Under Server Port Numbers change the value for Outgoing Server (SMTP) to: 587
  • Click OK, Next & Finish

The exact procedure may vary depending on your email software and version. If you are using the older name for incoming or outgoing mail server - this is OK, both will work.
