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 21:48:10 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:

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

 

Code:

$TTL 1W
@               IN SOA   linux-noob.com.  root.linux-noob.com. (
                            2008021808             ; serial (d. adams)

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.
