Hi all
I have a theory question related to the following scenario on spam control.
My email is eg: body@somebody.com my smtp server is not on this domain but somewhere else on the internet e.g. smtp.elsewhere.com. I smtp auth to this server to send mail. When the receiving server gets the mail it does a reverse query on body@somebody.com to smtp.elsewhere.com if the receiving server does not get on acknowledgement that somebody.com can send mail from smtp.elsewhere.com then the mail is rejected but this normally does not happen.
The question:
How does smtp.elsewhere.com store a sender address to answer reverse queries when the sender don’t exist on managed domains.
Or am I miss understanding how reverse smtp checks work.
Hope someone can answer or direct me to a document to explain.
Thanks
Ivan
