Here is what you do:
Get exim up and running first.
Add in this Transport to handle virtual deliveries.
# Deliver virtual domains to their own mail spool
virtual_localdelivery:
driver = appendfile
create_directory = true
directory_mode = 700
file = /var/spool/virtual/${domain}/${local_part}
user = exim
group = exim
mode = 660
This transport assumes that the spool directory is owned
by exim! If it isn't then
-> chown exim:exim /etc/virtual will do the trick
If you are not already up and running with exim just let me
know and I will share a script that can effectively get
your system up and running with Exim.
You can test your config with
-> exim -bt [virtualuser@???]
and you should see something like this:
<-- virtualuser@???
<-- virtualuser@???
deliver to virtualuser in domain virtual.domain.com
director = virtual_localuser, transport = virtual_localdelivery
This indicates that exim is properly handling virtual delivery.
With that behind, get a copy of vm-pop3d at
http://www.reedmedia.net/software/virtualmail-pop3d/#download
And as usual do:
tar -zxvf vm-pop3d-1.1.4.tar.gz
cd vm-pop3d-1.1.4
edit vm-pop3d.h setting:
#define VIRTUAL_UID 90 (which also owns the virtual spool - in my case exim)
This allows vm-pop3d to act as exim.
Then do:
./configure --enable-debug && edit config.h
and make this change
/* Define if you have the <security/pam_appl.h> header file. */
/* #undef HAVE_SECURITY_PAM_APPL_H 1 */
This knocks out PAM.
Then do:
make && make install
to make and install the application.
Finally, add this line to inetd.conf
pop stream tcp nowait root /usr/libexec/tcpd /usr/local/sbin/vm-pop3d
Please make sure of the availability of /usr/libexec/tcpd. I had to get mine
at
ftp://ftp.cert.org/pub/tools/tcp_wrappers/tcp_wrappers_7.6.tar.gz
Beware of Trojan Horse Versions of this.
The link above should be secure. Please see CERT Notification
http://www.cert.org/advisories/CA-1999-01.html
With Exim delivering and VM-POP3D installed, we are now ready for
deploying virtual domains.
For each virtual domain you would like to host do:
[ note: Make sure that /etc/virtual is owned by Exim]
cd /etc/virtual
mkdir [virtual.domain.com]
touch [virtual.domain.com]/aliases --> contains all address (aliases) for the
domain
touch [virtual.domain.com]/passwd --> contains all password for domain accounts
Your [virtual.domain.com] has been initialized. Next add in user accounts with:
echo [username]:[useraddress] >> [virtual.domain.com]/aliases
for example
-> echo [me]:[me@???]
to make me@??? valid
./authenticate [username] [password] >> [virtual.domain.com]/passwd
for example
-> ./authenticate me mypassword >> virtual.domain.com/passwd
to supply password for the account we just created
To create the script authenticate which generates encrypted passwords just do:
edit authenticate --> and then add the below lines
_______________________________________
#!/usr/bin/perl
# syntax authenticate username password >> file you are publishing to
$name = $ARGV[0];
@salt_chars = ('a'..'z','A'..'Z','0'..'9');
$salt = $salt_chars[rand(62)] . $salt_chars[rand(62)];
$passwd = crypt ($ARGV[1], $salt);
print "$name:$passwd\n";
_______________________________________
Then chmod 700 authenticate. if you like
ln -s /usr/sbin/authenticate /etc/virtual/authenticate
to make authenticate easily accessible
This script was gotten from
http://www.reedmedia.net/software/virtualmail-pop3d/#passwords
So we have successfully setup Exim to accept & delivery for virtual domains
and now our popper will be able to pick it up. Let's test it.
telnet localhost 110
user me@??? -> the account we just created
[+OK]
pass mypassword -> the password we supplied for that account
[+OK]
stat
[blah blah blah] -> the number of messages we have on the server
So that's it. CONGRATULATIONS! Without needing entries in /etc/passwd,
we have now setup our system to accept mails for multiple domains.
Any more problems, just shout and I will be glad to help you out some
more.
