Hello, Thank you for this wonderful resource. I have followed this tutorial: http://howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-debian-lenny I have gotten almost everything to work. I can retrieve my emails, but the problem is sending emails. My email clients (thunderbird, Mail.app) can't seem to connect to my outgoing smtp server. I checked and triple checked for any typos, none - made sure I replaced specific info (i.e ip addresses, domain names, etc.). I checked my mail log and that's the strange thing. I get no errors. When I open up my email clients and log in. It shows up in the log. But when I try to send out an email. Nothing the email client, just usually hangs. I realize there are a bunch of related posts. But none of them seem to be similar to mine. Thank you again for all your work in putting this site together. Any help will be appreciated.
