Valid From Address Printed From: LogSat Software Category: Spam Filter ISP Forum Name: Spam Filter ISP Support Forum Description: General support for Spam Filter ISP URL: https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5760 Printed Date: 15 December 2025 at 8:02pm Topic: Valid From Address Posted By: jasone Subject: Valid From Address Date Posted: 17 August 2006 at 5:00pm Is there a check within the spam system that checks to make sure that the senders email is valid before accepting it? Replies: Posted By: LogSat Date Posted: 17 August 2006 at 6:48pm There is not one to check if the actual email address itself is valid, but there are others to check if the domain specified in the address is valid (MX record test). There is also one (the SPF filter) that checks to ensure that the IP sending you emails is authorized by the owner of the domain name to send such emails. ------------- Roberto Franceschetti http://www.logsat.com" rel="nofollow - LogSat Software http://www.logsat.com/sfi-spam-filter.asp" rel="nofollow - Spam Filter ISP
