Postfix bouncing

[xDamox]

Hello,

 

I have recently tried to setup a Postfix machine but every time I try and send an email to the server it bounces:

 

Code:

Feb 18 21:48:09 linux-m899 postfix/pickup[5303]: B924D241BD: uid=1000 from=<damian> Feb 18 21:48:09 linux-m899 postfix/cleanup[6453]: B924D241BD: message-id=<20080218214809.B924D241BD@linux-m899.site> Feb 18 21:48:09 linux-m899 postfix/qmgr[5304]: B924D241BD: from=<damian@linux-m899.site>, size=415, nrcpt=1 (queue active) Feb 18 21:48:09 linux-m899 postfix/smtp[6455]: B924D241BD: to=<root@linux-noob.com>, relay=none, delay=0, status=bounced (mail for linux-noob.com loops back to myself) Feb 18 21:48:09 linux-m899 postfix/cleanup[6453]: F1181241BC: message-id=<20080218214809.F1181241BC@linux-m899.site> Feb 18 21:48:10 linux-m899 postfix/qmgr[5304]: F1181241BC: from=<>, size=2088, nrcpt=1 (queue active) Feb 18 21:48:10 linux-m899 postfix/qmgr[5304]: B924D241BD: removed Feb 18 21:48:10 linux-m899 postfix/local[6458]: F1181241BC: to=<damian@linux-m899.site>, relay=local, delay=1, status=sent (delivered to mailbox) Feb 18 21:48:10 linux-m899 postfix/qmgr[5304]: F1181241BC: removed

 

I have also setup DNS for the host:

 

Code:

linux-m899:/var/lib/named/master # dig MX linux-noob.com ; <<>> DiG 9.3.4 <<>> MX linux-noob.com ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 31140 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;linux-noob.com.

My linux-noob.com.zone file is like:

 

Code:

$TTL 1W @ IN SOA linux-noob.com. root.linux-noob.com. ( 2008021808 ; serial (d. adams) 2D ; refresh 4H ; retry 6W ; expiry 1W ) ; minimum IN NS linux-noob.com. linux-noob.com. MX 20 mail.linux-noob.com. linux-noob.com. IN A 172.25.147.177 www CNAME linux-noob.com. mail CNAME linux-noob.com.

 

Any ideas?

[magikman]

mydestination = $myhostname, $mydomain, localhost.$mydomain, localhost

 

Postfix is also very good at fighting spam without the need for different programs/scripts. Use the following in your config to use RBLs:

 

smtpd_recipient_restrictions = permit_sasl_authenticated,

permit_mynetworks,

reject_unauth_destination,

reject_rbl_client zen.spamhaus.org,

reject_rbl_client cbl.abuseat.org,

reject_rbl_client bl.spamcop.net,

permit

 

You can also do header checks and a whole host of other things. It can do lots of cool stuff.

 

:P

Hello magikman,

 

I found the problem, the mydestination directive was declared twice.. It was sneakily placed at the bottom of the main.cf file.
