I used to have a much higher rejection count; that comes and goes. A higher message count wouldn't matter much. [BTW in my current setup there are cases where connections can get closed that are not counted in the statistics, so I don't actually know how many email sending attempts there were.] > The other problem was some legitimate businesses are misconfigured so I was > rejecting legit invoice and shipping confirmation emails.

These problems don't simply go away when someone else hosts your mail -- instead you're trusting that your host provider will deal with them better. I just realized: I don't have a "spam" folder. Since I didn't miss it, I suppose that might mean I've gotten to the point where I don't need one, at least for the moment -- for however long that lasts. -- -- Chris Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) Vassar College Oct 3 - Mobile Web Development Nov 7 - Typography: Physical Art to Digital Art Dec 5 - Sysadmin Panel
