Hi,

Im trying to setup postfix, i've followed the basic steps on as described on postfix.org. But trying to telnet to localhost:25 yields no respone what so ever.

Does it matter how the systems domain name is set?
As of current i have it set in rc.conf as hostname.domainname.tld

Issuing
Code: 
domainname
, or
Code: 
sysctl -a | grep domain

Shows nothing.

Should i disable SASL and TLS until i got the basics working?

Here is the output of postconf -n

Check the log (/var/log/maillog). Postfix is quite verbose.
 
Logs are definitely the first place to check.

However, one thing that I noticed just doing a cursory look at your config is that mynetworks isn't set. This should be set to at least 127.0.0.1, reload postfix, and then try telneting to port 25 from the console.

Another thing to check is your firewall - it may be blocking connections on port 25.
 
Nevermind my comment about mynetworks - saw it on the last line of your output next to another line. (Guessing that the formatting got screwed up when pasted onto the forum?)
 
Are the postfix processes running?
Code: 
# ps -aux | grep postfix
root        717  0.0  0.3  3328  1536  ??  Ss    9:27PM   0:00.02 /usr/local/libexec/postfix/master
postfix     720  0.0  0.3  3328  1540  ??  S     9:27PM   0:00.01 pickup -l -t fifo -u
postfix     721  0.0  0.3  3328  1556  ??  S     9:27PM   0:00.01 qmgr -l -t fifo -u
postfix     839  0.0  0.3  3328  1540  ??  I     9:30PM   0:00.01 anvil -l -t unix -u

Is something LISTENing on port 25?
Code: 
# netstat -an -f inet

The telnet test
Code: 
$ telnet vintrax.utp.xnet 25
Trying 192.168.222.244...
Connected to vintrax.utp.xnet.
Escape character is '^]'.
220 vintrax.utp.xnet ESMTP Postfix
quit
221 2.0.0 Bye
Connection closed by foreign host.

And remember that without a properly configured DNS not anybody on the Internet can send mail to your server.
Not having a hostname for the postfix box, and probably not resolvable in DNS does not seem to be a promising start ;)

At least mine resolves in my local LAN ;)
 
First to check - which port he is listening:
Code: 
sockstat -lnp 25
Second - check its running at all
Code: 
pgrep -fl postfix
 
Hi,

Here are some output from ps and netstat

Code: 
ps -aux | grep postfix
postfix  1008  0.0  0.5  5312  2380  ??  I     7:50PM   0:00.02 pickup -l -t fi
postfix  1009  0.0  0.5  5312  2412  ??  I     7:50PM   0:00.02 qmgr -l -t fifo


Code: 
netstat -an -f inet
Active Internet connections (including servers)
Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)

tcp4       0      0 *.2200                 *.*                    LISTEN
tcp4       0      0 *.10100                *.*                    LISTEN
tcp4       0      0 *.10143                *.*                    LISTEN
tcp4       0      0 *.25                   *.*                    LISTEN

So it seems like it is listening, but all i get when i try a telnet to localhost on port 25 is
Code: 
 telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Edit Oops, in /var/log/messages i found this:
Code: 
parameter "smtpd_recipient_restrictions": specify at least one working instance of: check_relay_domains, reject_unauth_destination, reject, defer or defer_if_permit

You have to add reject_unauth_destination.

Code: 
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
 
Yes, of course, just send mail to it.

But without a hostname resolvable in DNS, that is only going to work on the postfix box itself, not from a remote box.So fix the hostname/DNS issue first.

Code: 
$ echo hello | mail -s 'test' business_woman
The mail should turn up in /var/mail. If not check the log files.
