If you are experiencing problems connecting to your SMTP server through Iguana, there are tools you can use to help you diagnose the problem:

• First, check whether your anti-virus software is interfering with your connection. You may need to reconfigure your firewall to ensure that connections to your SMTP server are not being blocked.
• If you are running Iguana on Mac OS X or Unix, you can use your telnet client to troubleshoot your SMTP server. This client is included as part of your operating system.
• When you use the Email Notification screen to send a validation email message, click the View SMTP log link:

When you click this link, a log of the attempt to connect to the SMTP server is displayed:

This may help you determine what is wrong with your SMTP connection.

• If you are running Iguana on Windows, you can use PuTTy, which is a free implementation of telnet and other network protocols for various platforms.

To use telnet on Mac OS X or Unix:

• In a terminal window, type telnet <hostname> <port>, replacing <hostname> with your SMTP server's host name (for example, mail.domain.com) and <port> with the server's SMTP port. (This port is usually 25.)
• If your host name and port values are correct, you should see a message similar to the following:

220 domain.com SurgeSMTP (Version 2.2c10-10) http://surgemail.com

• If the connection is successful, type quit to end the session. Use this host name and port value when configuring your email server settings in Iguana. (See Configuring the Email Server Settings for information on how to configure your email server settings.)
• If the connection is not successful, confirm the host name and port value with your network administrator.

To use PuTTY on Windows:

• Download and install PuTTY.
• Open PuTTY. The PuTTY Configuration window appears:

• You may need to change the telnet negotiation mode from active to passive. To do this, select Telnet from the Category panel and select the Passive radio button:

• From the Category panel, select Session to return to the basic options screen.
• In the Host Name field, type the host name of your STMP server.
• In the Port field, type the server's SMTP port. (This is usually 25.)

• Click Open. If your host name and port values are correct, you should see a message similar to the following:

220 domain.com SurgeSMTP (Version 2.2c10-10) http://surgemail.com

• If the connection is successful, type quit to end the session. Use this host name and port value when configuring your email server settings in Iguana. (See Configuring the Email Server Settings for information on how to configure your email server settings.)
• If the connection is not successful, confirm the host name and port value with your network administrator.
