Email Outbound not working.

I have an smtp relay setup in our environment. We use this successfully from all our ubuntu and windows boxes. We have verified there are no firewall issues.

When I am trying to test sending an email it returns the below. This is holding up our launch. since we cannot reset user passwords without this.

Error:The following From address failed: xxx@xxxx.com : MAIL FROM command failed,Send hello first ,503,5.5.2SMTP server error: MAIL FROM command failed Detail: Send hello first SMTP code: 503 Additional SMTP info: 5.5.2SMTP server error: MAIL FROM command failed Detail: Send hello first SMTP code: 503 Additional SMTP info: 5.5.2

Sorry, where (in which log) are you getting this error?

And what is your SuiteCRM version?

In SuiteCRM latest versions, 7.10, 7.9.14 and 7.8.15, in the “Send test email” buttons, when the sending fails, you find a link to see a “See full SMTP log”, that might help troubleshoot.
