Hello, 

I try to configure SMTP email, while testing got SMTP error: DATA END command failed: 530 From Header does not match MAIL FROM address. 
SMTP Error: data not accepted. 

I don't really see where I could set Header data in LimeSurvey Email configuration. Could you please point me, what should I do?
