Outgoing mail server (SMTP)

Specifies the mail server to use when sending an email message from a script.  If this is not specified, the sendmail script command will not work.

SMTP Port

Specifies the network port number on which the mail server accepts connections.  25 is the default (and usual) value for non-secure authentication.  Secure authentication usually uses port 465 or 587.  Check with your mail service provider if you don't know which port is used.

Authentication

Specifies the type of authentication used by the mail server.  If your server requires secure authentication, you may have to experiment with the three options to see which works.

Account

Specifies the username for the mail server.  (This will not be available if Authentication is set to "None".)

Password

Specifies the password for the mail server.  (This will not be available if Authentication is set to "None".)

POP3 Port

This is only available when Authentication is set to "POP3 Login".  110 is the default (and usual) setting.

Log mail communications to Activity Log (for debugging)

When checked, Ascendis Caller ID logs communications with the mail server to the Activity Log.  This is useful for debugging problems sending mail.
