I'm updating Sendmail Enabler to close down the Open Relay. The way it's set up now, it's an open hole for spammers to drive their drivel through. The original idea was to make it very easy for people to activate the built-in Sendmail feature in OS X. It seems to have succeeded because now I'm getting close to five downloads of Sendmail Enabler a day, making it about a hundred to date.
I was counting on people figuring out how to close the hole themselves because I just didn't have the time to add the enhancement that will let them close it and yet keep it open for selected domains. But maybe, a hundred open holes for the spammers is way too much.
So, being a responsible citizen, I will have a new version of Sendmail Enabler, due out later this week. That will close the hole - again with just one click.
