I've followed the how-to on Sendmail-SMTP-AUTH-TLS-Howto (http://www.howtoforge.com/howto_sendmail_smtp_auth_tls) on a fresh install of Fedora Core 8. All seemed to go just great with no prob's installing/configuring anything, no errors at all, until the end. The how-to states: To see if SMTP-AUTH and TLS work properly now run the following command: telnet localhost 25 After you have established the connection to your sendmail mail server type ehlo localhost If you see the lines 250-STARTTLS and 250-AUTH everything is fine. My output, however, only shows the following: ------------------ [root@mail-node-1 init.d]# /etc/init.d/sendmail start Initializing SMTP port.

Update I have since rebooted the server, and my output is now the following: [root@mail-node-1 ~]# telnet localhost 25 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 mail-node-1.xxxxx.net ESMTP ehlo localhost 250-mail-node-1.xxxxx.net Hello localhost.localdomain [127.0.0.1], pleased to meet you 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 15000000 250-DSN 250-ETRN 250-AUTH LOGIN PLAIN 250-STARTTLS 250-DELIVERBY 250 HELP It does not show "250-AUTH" - but does show "250-AUTH LOGIN PLAIN" I have tested sending mail through the server, and it accepts both whe the e-mail client is set for SMTP Authentication and when it is NOT set for SMTP Authentication. Is this normal, or did I miss something else? Thanks, Scott Miller
There was no /etc/postfix/main.cf file in that directory, but there was a main.cf-rpmsave file. I then installed postfix with "yum install postfix" and it installed: cyrus-sasl-2.1.22-8.fc8 postfix-2.4.5-2.fc8 Now, there's a main.cf file, and the mynetworks portion reads: #mynetworks_style = class #mynetworks_style = subnet #mynetworks_style = host #mynetworks = 168.100.189.0/28, 127.0.0.0/8 #mynetworks = $config_directory/mynetworks #mynetworks = hash:/etc/postfix/network_table all, however, are comented out. I then started postfix "service postfix start". Now, I can not send through it at all. Even after stoping postfix. I will start over on the how-to, removing; openssl, cyrusmail and sendmail. Maybe now that postfix is installed it should work? Scott Miller
That's ok. Where did you send to? If you send to recipients that are on the same server, then you don't need to authenticate. But if you send to externel email addresses, then you need authentication.
