postfix 2.1.1

after reading the article on this site about installing the new postfix v.2.1.1, i made a backup of my 10.3 server and decided to give it a try... i'm glad i made a backup. i got all of the errors described in the article and postfix seemed to work. i had to uncheck ssl for my smtp server settings in apple mail to send any outgoing mail, i kept getting tls is not supported by this smtp server message. all was fine until i restarted my server... no user could log in. i couldn't even log into the admin account on the server, so i booted off my 10.3 server disk and tried to reset the password and much to my surprize there were no users to reset passwords for??? i got confused at the step "Create the file ì/usr/lib/sasl2/smtpd.confî and i think this is where i ran into trouble. i created a file smtpd.conf in /usr/lib/sasl2 and wasn't sure this was correct. what permissions are used for this file??? i have no idea what happended and any suggestions would be greatly appreciated. thanks, charles
