Registry Settings

The following steps must be followed by an IT professional only. Any modifications other than the recommended ones may cause serious performance issues with the server and hamper the employees' work capability.

Name	Type	Default Value	Enable Value	Port Number	Comment
UseChilkat	DWORD	1	1	N/A	Chilkat API is the default email processing module used in Workflow unless the value is set to 0. If set to 0, an older module (developed in-house) will be used.

StartTLS	DWORD	0	1	N/A
UseEmailUserCredential	DWORD	0	1	N/A	If anonymous authentication for SMTP is the configuration then no need to set this registry value. Otherwise set its value to 1. If set to 1, password will be used for SMTP authentication.

UseOAuth2ForEmails	DWORD32	0			Registry Value: 0 - (Default). WF will use password-based authentication for both Get (POP3/IMPA4) and Send (SMTP) emails. 1 - WF will use OAuth2 only for POP3/IMAP4 (Get) emails. SMTP will use a password. It is a typical setup for an SMTP Relay server. 2 - WF will use OAuth2 only for SMTP (Send) emails. POP3/IMAP4 will use a password. This is not common. 3 - OAuth2 will be used for both POP3/IMAP4 and SMTP. If the value is 0, WF will not check if the email_auth_config table is set, or Enabled is set to Y or N. This will be checked only if the registry value is set to 1 or higher.
Email Throttle Interval	DWORD32	0	<Throttle Seconds>	N/A	Delay time between emails sent by Workflow (WF) engine. If changed from the default, WF engine sends one email at a time. Each outgoing email has a minimum gap of the number of seconds configured here. The default is 0, minimum is 1, and the maximum is 5 seconds. This configuration should be done only if absolutely needed due to an external email server terminating connections. The value should be as low as possible.
