I need some assistance here with a custom email server configuration please. When I attempt to set this up with the settings that I know are working for email clients Manager gives me a “Failed Recipients” Message. (The recipients have been checked and are valid).
The working Mail Server Settings for a client are as follows:
I think the issue is perhaps the last two items. Does Manager support STARTTL and Normal Password because if I attempt to connect to the IMAPI Mail server with any other setting for Authentication Method, eg. Kerberos or encrypted or NTLM the Email Client sending mail will fail? Something that is observed and important too, the first time an email client is setup and is connected to the mail server the email client has to accept a certificate. I do know how to OK / accept the certificate in Manager if occurring in the background for the Manager Server edition.
Manager sends email OK when not using the custom SMTP method.
