Configure secure imap – imaps

First of all check whether your mail server is running. If everything is going file, follow the steps –

1. Have backup copy of dovecot.pem file
cd /usr/share/ssl/certs
mv dovecot.pem org.dovecot.pem
cd ../private
mv dovecot.pem org.dovecot.pem
cd –

2. Create new dovecot.pem file with your customized setting, execute make
dovecot.pem. See the screen shot below


At this point your system will ask you to supply some information like – Country name
etc. See what I have done in my case below –



Carefully note the Common Name section. Here, you must supply the FQDN of your mailserver.
At this point the /usr/share/ssl/certs/dovecot.pem is created. If there is any problem, remove the dovecot.pem file and recreate it.

3. Copy the file to /usr/share/ssl/private directory –
cp dovecot.pem ../private
4. Modify /etc/dovecot.conf file as follows –
protocols = ipop3 pop3 imap imaps
5. Restart the servers –
service dovecot restart
service sendmail restart
