== Activation of Qmail2 ==

Changes on Qmail2-Send run file 

 vi /service/qmail2-smtpd/run

( add following line at the top )

 <nowiki>#!/bin/sh</nowiki>
 QMAILQUEUE="/var/qmail2/bin/qmail-tail"; export QMAILQUEUE

Also Make sure the Qmail-smtpd is running on port 900 by 

vi /etc/services

 <nowiki># Local services</nowiki>
 second-qmail 900/tcp


Integrate Qmail with Qmail2 

vi /var/qmail/control/smtproutes

 :127.0.0.1:900


Note: Then restart the qmail from /etc/inittab file.


== Testing ==

# telnet and send mail via Qmail-2 , you should get the disclaimer 
# Test via offline Client like Evolution , Outlook etc . You should get the mail with disclaimer attached .

== Troubleshooting ==

1. QQ error while sending mails

Check the smtp logs , if find error like 

''/usr/local/bin/qmail-qfilter: error while loading shared libraries: libbg-sysdeps.so.1: cannot open shared object file: No such file or directory''

Then 

you have to link libbg-sysdeps.so.1  to /usr/lib 

 ln -s /usr/local/bglibs/lib/libbg-sysdeps.so.1 /usr/lib/

This should solve the issue

2. Some time the Qmail-1 is not able to deliver mails to Qmail-2 instance due to /var/tmp/qmail-qfilter directory is not there or vanishes. So a script to check and create the directory with cron is created for taking care of this issue.

The script  is /usr/bin/check_qmail-qfilter_dir.sh

 #!/bin/sh
 DIRECTORY=/var/tmp/qmail-qfilter
 if [ ! -d "$DIRECTORY" ]; then
 mkdir -p $DIRECTORY;
 chmod 777 $DIRECTORY;
 chown -R root.qmail $Directory
 fi

The cron entry is as follows 

 */5 * * * * /usr/bin/check_qmail-qfilter_dir.sh
