Howto: Virtualmail with Sendmail plus virtualusers connecting to courier-imap.

I'll set this up in a jail and I will need to write into /usr/libexec/sm.bin folder (man smrsh). So in /etc/fstab you will need rw for this jail.
example

Code:

/home/j/mroot   /home/j/mx2    nullfs  rw  0   0

Inside Jail:

Code:

echo '192.168.0.1 mail.columbiangold.ca' >> /etc/hosts

Configuring sendmail:
/etc/mail/virtusertable

Code:

test@columbiangold.ca user1.virtual
paul@columbiangold.ca user2.virtual
@columbiangold.ca user2.virtual

/etc/mail/aliases (I placed this at the bottom of the file.)

Code:

user1.virtual: |/usr/libexec/sm.bin/user1.virtual
user2.virtual: |/usr/libexec/sm.bin/user2.virtual

/etc/mail/local-host-names

Code:

columbiangold.ca
mail.columbiangold.ca

/etc/mail/access

Code:

192.168.0.1                          RELAY

change directory to /etc/mail

Code:

make

Install procmail

Code:

portmaster mail/procmail

/etc/mail/mail.columbiangold.ca.mc
add procmail above: MAILER(local)

Code:

FEATURE(`local_procmail', `/usr/local/bin/procmail -t -Y -a $h -d $u')
MAILER(local)
MAILER(smtp)

change to directory /etc/mail and again do this.

Code:

newaliases
make

/usr/libexec/sm.bin/user1.virtual

Code:

/usr/local/bin/procmail /usr/local/etc/procmailrcs/user1.virtual

/usr/libexec/sm.bin/user2.virtual

Code:

/usr/local/bin/procmail /usr/local/etc/procmailrcs/user2.virtual

/usr/local/etc/procmailrcs/user2.virtual

Code:

PATH=/bin:/usr/bin:/usr/local/bin
MONTHYEAR=^Date +%y%m
VHOME=/home/mail/domains/columbiangold/mail/paul
LOGFILE=/home/mail/domains/columbiangold/logs/user2.virtual/log
LOGABSTRACT=all
VERBOSE=on
# Spam filter
:0fw
| /usr/local/bin/spamc

:0:
* ^X-Spam-Status: Yes
$VHOME/spam


:0:
$VHOME/inbox/

Install p5-Mail-SpamAssassin & add SPF_QUERY support

Code:

portmaster mail/p5-Mail-SpamAssassin

Code:

install -v -m 0764 -o mailnull -d /home/mail/domains/columbiangold/mail/test
install -v -m 0764 -o mailnull -d /home/mail/domains/columbiangold/mail/paul
install -m 0700 -o mailnull -d /home/mail/domains/columbiangold/logs/user2.virtual
install -m 0700 -o mailnull -d /home/mail/domains/columbiangold/logs/user1.virtual

Install courier-imap & select AUTH_USERDB

Code:

portmaster mail/courier-imap

After imap is installed run

Code:

pw2userdb

and copy your user info's 2 lines:

Code:

mailnull	uid=26|gid=26|home=/var/spool/mqueue|shell=/usr/sbin/nologin|systempw=*|gecos=Sendmail Default User
26=	mailnull

and copy to this file:

Code:

mkdir /usr/local/etc/userdb
vi /usr/local/etc/userdb/default

Code:

makeuserdb

/usr/local/etc/authlib/authdaemonrc change authmodulelist=
this will avoid syslog messages.

Code:

authmodulelist="authuserdb"

/etc/rc.conf

Code:

spamd_enable="YES"
spamd_flags="-A 192.168.0.1 -u spamd -H /var/spool/spamd"
courier_imap_imapd_ssl_enable="YES"
courier_imap_imapd_enable="YES"
courier_authdaemond_enable="YES"

change permissions to quell authdaemond err. and start authdaemond

Code:

chmod 0700 /usr/local/etc/userdb
/usr/local/etc/rc.d/courier-authdaemond start

now run authenumerate to place text in a file. and add a home path for mailnull inline to the virtual mail directories. Notice every textgroup has a tab spacing.

Code:

authenumerate -s > /usr/local/etc/courier-imap/shared/index
vi /usr/local/etc/courier-imap/shared/index
mailnull        26      26      /home/mail/domains

man userdb (order and the no last foward "/" execpt specifying the Maildir 'like so here and in procmailrcs/columbiangold file')

Code:

userdb columbiangold/paul@columbiangold.ca set home=/home/mail/domains/columbiangold/mail/paul mail=/home/mail/domains/columbiangold/mail/paul/inbox/ uid=26 gid=26

man userdbpw

Code:

userdbpw  | userdb columbiangold/paul@columbiangold.ca set systempw

Code:

makeuserdb

Missed some file changes: So also run

Code:

chmod -R 0700 /usr/libexec/sm.bin/*
chown -R mailnull /usr/libexec/sm.bin/*
chown -R mailnull:mailnull /home/mail/*

At this point log out of the jail and double check your firewall for port 143 and 25 access if this is a VPS remote server and /etc/natd.conf always to redirect port 143 and 25. restart if necessary or just restart your jail. Also remove read/write permission that were changed in the file fstab.

Thanks for using the guide.

When you test connect to the imap-server use no-encryption with this setup.

https://www.cacert.org/ for a free certificate.

If your not seeing your mail or not authenticating check /var/log/maillog on the server.

Please denote to the FreeBSD foundation i did.
