Hello, I am a complete noob on Linux, and I followed the instructions for installing the "perfect server" from how to forge site as sort of training for my job. However, I cannot send or receive mail using either squirrelmail or outlook unless I disable SSL. However, since this is for business use, we cannot send our email without SSL. The error message I am getting is: "Sending of message failed. The message could not be sent because connecting to SMTP server 192.168.35.175 failed. The server may be unavailable or is refusing SMTP connections. Please verify that your SMTP server settings are correct and try again, or contact the server administrator." I thank you in advance for any help. tbunn OK, boss gave me more info... The problem is with sending email using SMTP, outlook or thunderbird.
