Enabling SMTP exceptions to authenticated hosts (R5.0.6)

Typically, when Anonymous SMTP Access is turned off in the server document, Authentication is required. This is configured in the server document via Ports -> Internet Ports -> Mail -> SMTP InBound (Authentication Options: Name & Password = Yes AND Anonymous = No). With R5.0.6, a new feature is added, allowing for an exception list of hosts and/or IP addresses that are not required to Authenticate when SMTP authentication is required (Anonymous SMTP Access is turned off ). This is enabled via a new NOTES.INI parameter, SMTPAllowConnectionsAnonymous=1.

This Exceptions List is maintained in the Server Configuration document (Router/SMTP -> Restrict. & Controls -> SMTP InBound Controls), in the field "Allow connections only from the following SMTP internet hosts/IP addresses".

Because of Microsoft WINS/DNS issues on NT 4.0, it is recommended that you use IP Addresses in the form [nnn.nnn.nnn.nnn], instead of host names.
