I have Sharepoint and on the same box i have the smtp service enabled. I only need to send out alerts and workflow notifications to external email addresses and do not care about incoming email and i do not have a mail management program like Exchange installed..
1) Can i send out external emails with only the smtp service and no actual mail mgmt program such as Exchange? In the SP outgoing email config, I merely put the name of the machine that has smtp enabled (same machine that SP is installed on). Seems like there needs to be more to actually make this work.
2) If I need a program such as Exchange, can I instead have my smtp service receive an email request from SP and forward them to an external email service that I purchase? I'm hoping that the smtp service builds the message, but then can forward it to an external mail service that would actually send it out:
