If you can receive POP email but are unable to send messages, the problem may be related to a known issue.

In some cases, your Internet Service Provider (ISP) may  block  access to this system's SMTP (outgoing) email server. This behavior varies and depends on the ISP you use to connect to the Internet. ISPs sometimes do this to  prevent spam email from being sent using their networks.

The best way to overcome this is to set up an alternative 'port' to send your mail through.

By Default, email software will set the SMTP 'port to '25', which is the standard port for the SMTP protocol.  However our mail service has two alternative ports available that you can send through.

These are: 8025 or 587

You can usually adjust the SMTP port that your software uses under the 'More Options' or 'Advanced' area of the account setup.

If this does not work for you (as possibly these two additional ports are also blocked by your ISP for some reason), another alternative is to use your ISP's SMTP outgoing server information rather than using the outgoing server provided by this system.

If you are not sure what your ISP's SMTP server information is, try looking at the settings for one of your other existing email accounts.

If that information is not available from within your email client, contact your ISP to find out your SMTP server's address. Alternatively, visit their  website and search for the terms: setting up email.
