Sorry for the long post but I am really trying to understand why this isnt working. I have verified with 2 techs at my ISP that they are not blocking any ports. (wanted to clear that up right away)
I have a machine set up at home (RedHat 8 fully up2date) and it is running sendmail. I can receive mail just fine and send mail locally on my LAN to both internal and external recipients. I have set up SMTP AUTH and want to be able to send mail from outside my network using my smtp server and authenticating against my username. I believe all this is set up correctly according to this website http://www.joreybump.com/code/howto/smtpauth.html. When I try to send an email (using Outlook Express) I get the following error: The connection to the server has failed. Account: 'xxx.homedns.org', Server: 'xxx.homedns.org', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10054, Error Number: 0x800CCC0E The actual hostname has been replaced with xxx. I have a DSL router allowing port 25 and 110 to my Redhat box. I can receive email fine remotely using pop. I have no other firewall set up atm. When I tried the following command to test the connection, nothing is written to test.log sendmail -bD -X test.log It is acting like the request is never even getting to sendmail to begin authentication. Here is my sendmail.mc file for reference divert(-1) dnl This is the sendmail macro config file.
