Troubleshooting

If you cannot send emails please make sure that your email client has been setup properly. If you haven't already, please follow the setup instructions for your email software.

In particular, check the following:

  1. Your Email Address:
     Check that the email address you are sending from (the one in the 'From' field) matches either a domain name or an exact email address in your account. You can change your domain names/email addresses by logging in.
  2. Outgoing Server:
    Check that the Outgoing Server (this is the SMTP Server) in your email software is set to smtpcorp.com.
    If you are unsure where to find this, please refer to the setup instructions.
  3. SMTP Username and Password:
    Check that the you have entered your SMTP Username and Password in your email software correctly. If you are unsure where to find these settings, please refer to the setup instructions. You can find out which values you should enter by logging in.
  4. Port Number:

SMTP2Go Corporate works on ports 25, 2525, 8025 and 587. To determine if a particular port is blocked from your location, please do the following in Windows.
(Note: Windows Vista users may need to install Telnet to perform the test below, as Windows Vista does not come with Telnet pre-installed. To add Telnet in Windows Vista, go to Control Panel -> Programs -> Turn Windows Features On or Off and check Telnet Client).

  1. Click the Start button, and then click "Run..."
  2. Enter "cmd" and press Enter
  3. In the window that appears enter "telnet smtpcorp.com 2525". If port 2525 is available you should see "220 smtpcorp.com ESMTP Exim". If this does not appear, then close the window and repeat the steps above, using port 25 or 8025. For example, to test port 8025 enter "telnet smtpcorp.com 8025".

In almost all cases using port 2525 will work, however some ISPs may block port 2525. In these cases using the port number that you have determined is able to work above will solve the problem. Important- some PDAs (e.g. iPhones) do not have a separate field in which to enter a port number. In this case it is recommended that you set the Outgoing Server as smtpcorp.com:2525 (the port number must follow the server name, separated by a colon).

In the unlikely event that none of the above ports is working in your situation, please try using the following setup:
     SMTP server: port80.smtpcorp.com
     Port: 80

Problems sending large attachments are normally caused by a slow upload speed at your current location. You can check your current potential upload speed here: speedtest.net. At slow upload locations, we recommend sending a zip file of your attachments, or using sendspace.com.

If emails are being sent, but not arriving at their destination, please follow our guide: Improving Deliverability.
