Created a new process which should send an e-mail to a user and see the following:
Unable to send message to all the addresses
OK Adresses:0
OK undelivered Addresses:0
Not OK Addresses:1
Normally this error occurs the logs when one e-mail in a group is invalid. By default if one e-mail address has an issue Process Auto returns this error.
Open your Oasisconfig.properties and set the following:
mail.smtp.sendpartial=true
If the setting does not exist, add it to the bottom. Once complete restart Process Auto service. If this not resolve the issue continue below.
From the Process Auto machine can you telnet to the exchange on whatever port you are using (usually port 25)?
Process Auto Mail Module has both incoming and outgoing details on one screen in 4.2 where as these settings were separated in 4.2SP2 and above. If using the E-mail module enter the login information directly in the operator instead. Confirm the authentication to the smtp server is filled in at the operator level and try again.
Please also check to see if the e-mail address is an external address. If an external address we need to allow the PAM server to send external emails (through Outlook or your Exchange)
