Migrating postifx

[mgideon]

I'm getting rid of an older server and trying to migrate/setup a new server. This new machine is Mandrake 10.1. I have almost everything over, but I'm having problems with Postfix. I did a postconf on the old one and added what I thought was right to the new main.cf. Here is that postconf -n

alias_maps = hash:/etc/postfix/aliases, hash:/var/lib/mailman/data/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/lib/postfix
delay_warning_time = 4h
html_directory = /usr/share/doc/postfix-2.1.4/html
inet_interfaces = localhost
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, $mydomain, mydomain.com
myhostname = gate.mydomain.com
mynetworks_style = subnet
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix
owner_request_special = no
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.1.4/README_FILES
recipient_delimiter = +
relayhost = [smtp.sbcglobal.net]
sample_directory = /usr/share/doc/postfix-2.1.4/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) (Mandrake Linux)
smtpd_sasl_path = /etc/postfix/sasl:/usr/lib/sasl2
unknown_local_recipient_reject_code = 450

Probably stupid, but I just copied the aliases and .db, sasl_passwd and .db, and transport and transport.db files over. I really don't get the post map thing. I remember the headaces of setting it up the first time.

So I can send mail through the internet. I can't receive mail from the internet or other internal users. My domain and MX records seem okay ( I used to get mail from the other server ). There aren't any errors in my mail log. Info log shows the mail going out, but nothing is recorded when I try sending to my server. The old version of postfix was 2.0.13. My new one is 2.1.4.

Can anyone steer me in the right direction?

Thanks,
Mike

There's nothing in the mail log when you send a mail to the server? This probably means that you use another server for sending. Please check the email client settings, especially the SMTP server, and double-check the MX records.

I finally got my messages bounce back. I'm not getting errors because the connection isn't even getting made. If I telnet myhost.com 25, I get "Could not open connection to host on port 25. Connection failed."

netstat says
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN

I did some research. Seems I need an external interface listening for smtp.
I tried adding
myhost.com:25 inet n - n - - smtpd
to my master.cf, but postfix wont' run. postfix status says "master not running".

From that machine I can telnet localhost 25 and get a connection. How to I allow for an external connection?

Thanks!

Change the value of inet_interfaces to all in /etc/postfix/main.cf.

Undo this change and restart Postfix.

That made so much sense. But it didn't work. I still get connection refused and only

[root@gate postfix]# netstat -nl | grep 25
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
unix 2 [ ACC ] STREAM LISTENING 167825 private/lmtp-filter


I reloaded postfix and the netowork interface.

What's in your /etc/postfix/main.cf (leave out the comments)?

[mgideon]

here is my main.cf

queue_directory = /var/spool/postfix
mail_owner = postfix

# User configurable parameters

That line should read

mailbox_command = /usr/bin/procmail -Y -a $DOMAIN

Change it and restart Postfix.

[mgideon]

That was it. A cut and paste mistake. Dang I never would have found that. Thanks! My only other problem is all root mail is being delivered to the postfix account. BUT, at least it is going somewhere.

Thanks again,
Mike

Check out your /etc/aliases file.
