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/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

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

Any ideas?

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.
