SMTP Server Settings

Standard delivery, Direct delivery

Direct delivery is the default setting because it is the simplest to use. Unfortunately it frequently does not work due to anti-spam restrictions that may have been established by your ISP or by the companies receiving your email. For a detailed description of direct delivery on Gammadyne's web site click here:

For standard delivery you must have access to an SMTP server. There are several possibilities for obtaining access to an SMTP server.

SMTP server address

The address of the SMTP server will depend on whose server you are using. If you are using the address of the server was specified in the email you received when you signed up for their service.

SMTP server port

Like the SMTP server address, the port number will depend on whose server you are using. The standard port number for SMTP is 25, but this will likely be different if you are using a rented server. Some servers use port 587 instead of port 25.  This circumvents ISP's who block port 25. Port 465 is reserved for SMTP over SSL.  For this port to work, SSL/TLS Encryption must not be set to "None".

SMTP authentication

If you are using your own business's web server, then authentication may not be required, but a rented SMTP server will almost certainly require that you login with a username and password that they provide. This will not be the same as the username and password you use to retrieve email.

SSL/TLS encryption

Using encryption ensures that the credentials for access to the SMTP server are transmitted over a secure encrypted connection. Possible settings are:

None - No encryption is used.

Optional - If encryption is supported by the SMTP server, it is used.  If not, an unencrypted connection is used.

Required - If the server does not support SSL/TLS encryption, the operation will fail.  However, the server certificate is not verified.

Certified - Same as "Required", except the operation will also fail if the server certificate fails verification.
