I am attempting to be a Windows to Ubuntu convert so please excuse my ignorance. I have installed Postfix, Courier, etc onto UBUNTU 8.04 Beta. I used Falko's "Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 7.10)". Everything with well until I was done. It doesn't work and I am extremely frustrated. Had to make a few minor adjustments like apt-get install libdb4.6-dev instead of 4.5 and had to do a apt-get update before that. Here is my setup and what I am trying to do: I have 2 FQDN that I can use: example1.com and example2.com I do not do my own DNS but setup my domains through Dotster. I generally don't use mail.example1.com but rather just use example1 as my mail server name. I have a static IP that I think I have setup properly on the machine itself because I do have internet access. My machine name is: Memphis. I do not have a domain setup for my machine. In the main.cf file for postfix I use myhostname=example1.com I then setup for example1.com and example2.com in the domain table and setup several users for each domain. Here are some of the log entries: pop3d: chdir example1/user/: No such file or directory (Do I need to setup a directory on my drive for every user? That is what I was trying to avoid. postfix/smtpd[12784]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 451 4.3.0 <[email protected]>: Temporary Lookup failure; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<ME> I just don't even know where to start. Please help.
Additional info when I quit out of my telnet localhost 25 session after getting the Temporary Lookup failure, I get the following error: virtual_alias_maps map lookup problem for [email protected] Thing is I don't have a postmaster account and not sure why it tries to use one.
getting closer OK I actually have some of this working. I had the wrong field in one of my mysql statements which was giving me the error. Not sure how that happened because I was copying and pasting from the tutorial. Oh well. Now I can send email from telnet. I sent a test message to my gmail account and received it fine. When I replied to the email that also worked. I have Outlook setup with POP3 and it receives fine but when I attempt to send and email using Outlook it gives me an immediate response back saying message could not be delivered 550 5.1.1 <[email protected]> User unknown; rejecting Any ideas? I also changed my hosts file and my interfaces file. interfaces was missing auto eth0 and I added my static IP into the hosts file xx.xx.xx.xx mail mail.example1.com
Update Current situation: -Can send from linux machine using telnet localhost 25 without issue. -Cannot send from another machine (i.e. Windows machine with Outlook) even with SMTP authentication enabled.

Is this a good fix I got it to work by doing the following: chmod 777 /var/spool/postfix/var/run/saslauthd 1. Why did I have to do that? 2. Is it safe?
Problem with 777 chmod fix This fix works fine until you restart your computer. I would imagine it would do the same by simply restarting saslauthd. I have looked through /etc/init.d/saslauthd to find where it changes permissions back but can't find any chmod command listed. What else should I look for? Is there another way around this permission problem?
Did you configure saslauthd exactly as shown in chapter 6 on http://www.howtoforge.com/virtual-users-and-domains-with-postfix-ubuntu-7.10-p3 ?
Configuration is to HOW-To Instructions I have verified that everything is correct. I have included files below: /etc/default/saslauthd Code: START=yes DESC="SASL Authentication Daemon" NAME="saslauthd" MECHANISMS="pam" MECH_OPTIONS="" THREADS=5 OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd -r" /etc/pam.d/smtp Code: auth required pam_mysql.so user=mail_admin passwd=xxx host=127.0.0.1 db=mail table=users usercolumn=email passwdcolumn=password crypt=1 account sufficient pam_mysql.so user=mail_admin passwd=xxx host=127.0.0.1 db=mail table=users usercolumn=email passwdcolumn=password crypt=1 /etc/postfix/sasl/smtpd.conf Code: pwcheck_method: saslauthd mech_list: plain login allow_plaintext: true auxprop_plugin: mysql sql_hostnames: 127.0.0.1 sql_user: mail_admin sql_passwd: xxx sql_database: mail sql_select: select password from users where email = '%u' ls -la on /var/spool/postfix/var/run/saslauthd Code: drwxrwxrwx 2 root sasl 4096 2008-04-06 23:24 . drwxr-xr-x 3 root root 4096 2008-04-05 13:57 .. -rw------- 1 root root 0 2008-04-06 23:24 cache.flock -rw------- 1 root root 945152 2008-04-06 23:26 cache.mmap srwxrwxrwx 1 root root 0 2008-04-06 23:24 mux -rw------- 1 root root 0 2008-04-06 23:24 mux.accept -rw------- 1 root root 5 2008-04-06 23:24 saslauthd.pid The contents of the saslauthd.pid is 5738.

Add't info here is the ls -la of /var/spool/postfix/var/run/ after a reboot. Code: drwxr-xr-x 3 root root 4096 2008-04-05 13:57 . drwxr-xr-x 3 root root 4096 2008-04-05 13:57 .. drwx--x--- 2 root sasl 4096 2008-04-07 15:09 saslauthd
Is this proper I found in a couple of forum articles and another Howto the following: Add: adduser postfix sasl ln -s /var/spool/postfix/var/run/saslauthd /var/run/saslauthd Are the above good fixes? Your thoughts would be appreciated. Keith
