Darragh, I have been struggling with that problem too, and have just solved it this afternoon, thanks to some older correspondence with Chris Moore which did the trick for me. I have just switched to a DSL connection with verizon.net and they required authentication on their outgoing mail server. Here is an outline of what I had to do on my Slackware 9.1 Linux: 1. Obtain and install a package called "cyrus-sasl", a simple authentication and security library; 2. Get the source package for sendmail and recompile it, giving it information about the above package. 3. create a specialized sendmail.cf configuration with information about authentication; and 4. create a data base in /etc/mail called "authinfo.db" with your user name and password information. These are the general steps. The details are in the docs, and I will be glad to follow up privately if you want to correspond about it. I don't think anything in the above steps are distribution specific, by the way. Chuck On Sun, 30 Nov 2003, Darragh wrote: > Hello again, > I'm trying to get sendmail to use authentication.

I then click advanced and check Same as Incoming. If I don't do this I cant send mail. > > Any ideas? > > > Thanks > > > Darragh > _______________________________________________ > Speakup mailing list > Speakup at braille.uwo.ca > http://speech.braille.uwo.ca/mailman/listinfo/speakup > -- The Moon is Waxing Gibbous (52% of Full) Get my public key from website, http://www.mhonline.net/~chuckh
