Hey! Andrew! It works! Well I'll be damned! It works! I do not seem to need either the smtp of my ISP or the smtp of the new service at all. For some strange reason I had got into the habit of defining a "smart host" in my sendmail configuration which forces all my outgoing mail to be funneled through someone else's smtp service, when all the while I have a perfectly capable full service smtp right here on my own box! Here is my acid proof test (tell me if I am mistaken): (adult language follows) My ISP novocon.net screens incoming and outgoing mail for objectionable language, and when found, mail is bounced with error 550: "Your spam is not welcome here" I agree with Mark Twain that profanity provides a degree of relief that is denied even to prayer, and furthermore I do not appreciate filters perusing the contents of my incoming and outgoing email. Consequently when the phrase "enlarge your penis" appears in email reaching my ISP, it is bye-bye email. With "smart host" in sendmail set to "mail.novocon.net" (their smtp) I get bounced when trying to send such a message (and probably other phrases as well) but when I remove the "smart host" configuration, I can send such messages without hindrance. I guess I don't need authentication on my new service at all, since obviously I am already authenticated to use my own sendmail. Many thanks for pointing that out, Andrew. I have been busting my brain trying to solve a non-problem.
