I am trying to make a new probe for SMTP that checks for authentication here is what I have so far

Send: helo test.com
Receive: ^250.*
Send: mail from: test@test.com
Receive: ^250.*
Send: rcpt to:somevaliduser@domain.com
Receive: ^250.*

I keep getting a timeout is there any way that anyone can suggest for a proper way to check SMTP Authentication on a Probe?
