I'm upgrading a box from redhat to suse 8.1 pro. One task this box will assume is SMTP host. I've been using sendmail on the redhat box, but am interested in using postfix provided I can get it working. :) Here's what I changed in /etc/postfix/main.cf: myhostname = somehost.domain.com mydomain = domain.com myorigin = $mydomain After starting postfix, I can send mail from the localhost and the command line using this: echo "a test" | /usr/sbin/sendmail jejonas@yahoo.com But I'm not able to connect to postfix from another host using: telnet somehost 25 The connection is terminated and nothing is logged in /var/log/mail or /var/log/messages to indicate what the issue may be. Any insight is appreciated. I really don't want to go back to sendmail, but then this problem doesn't appear to be a postfix config issue either. Thanks! Jason
