SMTP channels

The SMTP channel is used to send out E-mail messages using the SMS Server.

Find more information about channels in general here.

The number of simultaneous SMTP channels you can configure depends on the license tier of your SMS Server installation.

Item Description
Server The host name or IP address of the SMTP server. For instance “smtp.yourdomain.dom” or “”.
Port The TCP port to connect to the SMTP server. This should normally be 587 but older server may also use 465 (secure) or 25.
Secure connection Check this if the connection to server should be secured. Please note that this normally only needs to be checked when the port number is 465.
When the port number if 587 or sometimes when it is 25 the connection will often be secured shortly after connecting (STARTTLS). In that case this box does not need to be checked but the connection will be secure anyway.
Mail server requires authentication Some SMTP servers require authentication before you can actually send SMTP messages. When you enable it, you must also provide a valid ‘Account’ and ‘Password’.
Account Name The Account Name property is used to log on to the SMTP server.
Password The Password property is used to log on to the SMTP server.
Full Name Friendly name of the sender. It will be shown as the sender’s friendly name by most POP3 clients.
E-mail Address E-mail address. This address will appear as the sender’s address by the recipient’s POP3 client.
Reply Address Reply address. If this address is not set the ‘E-mail Address’ will be the reply address.
Retry (ms) The time (MS) that the SMTP channel will wait before attempting to retry the connection to the SMTP server if the initial connection fails.
Send interval (ms) The time (MS) between sending each E-mail. Use this property to throttle an SMTP connection and limite the number of e-mail messages per second.
