Hi folks, I'm closing in on what I thought should be pretty straight forward, but my eyes are crossed from wading through all the HowTos and the Googled links to links to links, etc., so hopefully someone here can point me in the right direction. I've configure an Ubuntu 8.04 server to run Postfix with postfixadmin, mysql, smtp-auth using sasl, courier for imap and pop, and multiple webmail interfaces. I seem to have almost everything working since I can receive mail OK, send mail fine via the webmail interfaces, create new domains/users, etc. The one thing I can't seem to do is send email normally through TBird or c/l telnet methods. When I try to send mail I'm getting the following error: warning: SASL authentication failure: cannot connect to saslauthd server: Permission denied How do I track down what it's being denied permission to access?
