Hi, I am a bit new to Linux, but this guide is fairly simple to follow (thanks Falko!) but Ive ran into a bit of a snag. So far the only issue I ran into during installation/setup is that mysql says its only listening to localhost and not localhost.localdo like the guide says it should when doing netstat -tap | grep mysql So I went ahead and continued through the rest of the guide without a hitch! But when I attempt to send a message using mailx to a test account I receive this error in the mail.log (Ive renamed some things for security): MailServer1 is my host name my.domain.net is my virtual domain ct 15 18:22:17 MailServer1 dccproc: no working DCC servers dcc1.dcc-servers.net dcc2.dcc-servers.net dcc3.dcc-servers.net ... at 22.214.171.124 209.169.14 Oct 15 18:22:17 MailServer1 postfix/smtpd: connect from localhost[127.0.0.1] Oct 15 18:22:17 MailServer1 postfix/smtpd: 91EA53656285: client=localhost[127.0.0.1] Oct 15 18:22:17 MailServer1 postfix/cleanup: 91EA53656285: message-id=<[email protected] Oct 15 18:22:17 MailServer1 postfix/qmgr: 91EA53656285: from=<[email protected] Oct 15 18:22:17 MailServer1 postfix/smtpd: disconnect from localhost[127.0.0.1] Oct 15 18:22:17 MailServer1 amavis: (16961-05) Passed CLEAN, <[email protected][email protected][email protected] Oct 15 18:22:17 MailServer1 postfix/smtp: A9D6C3656286: to=<[email protected] Oct 15 18:22:17 MailServer1 postfix/qmgr: A9D6C3656286: removed Oct 15 18:22:17 MailServer1 postfix/smtp: 91EA53656285: to=<[email protected] At first glance I thought "Oh! It cannot find my domain, lets hard set our hosts file to say my.domain.net points to 127.0.0.1, but that didnt work. What is strange is that if I set up a forward in my forwards table and send a message to the origin address it does forward to my destination address so it would appear postfix is talking to the mysql database. Also if i set up a cc in a message using mailx I will receive it on the ccd address so it appears transport is working. I just cant seem to get the mail back into the box to create the maildir. So lastly I attempted to send a message from my exchange server and pointed the message to [email protected] Oct 15 18:43:18 officemail1 postfix/smtpd: connect from exchange.other.domain.net[192.168.*.**] Oct 15 18:43:18 MailServer1 postfix/smtpd: warning: Illegal address syntax from exchange.other.domain.net[192.168.1.13] in RCPT command: <[email protected] Oct 15 18:43:18 MailServer1 postfix/smtpd: disconnect from exchange.other.domain.net[192.168.*.**] Ive added the subnet that the exchange server resides on into mynetworks in the main.cf of postfix, yet I still receive this error. Any ideas on what may be wrong? Does this have anything to do with mysql only listening for localhost and not localhost.localdo? If there is anything else I need to provide just ask and thank you in advance for any help you can provide.
