Not sure if you resolved the issue, if not:
1st, please have a look at Usage Note 18363 (Troubleshooting guidelines for successfully sending an SMTP e-mail from SAS® software).
Can you send an email that way.
Then using instructions and sample code from Usage Note 19767 (Using SAS® software to send SMTP email), does it work?
Hope that helps.
Cheers,
