#The Courier-IMAP package includes 4 servers that can be individually
enabled/disabled : IMAP, IMAP-SSL, POP3, POP3SSL. In this example, we
are using the IMAP IMAP-SSL and POP3-SSL server.

vi /usr/local/courier-imap/etc/imapd
MAXDAEMONS=40 <– Max number of IMAP daemons

MAXPERIP=40 <– MAx connections per ip
IMAP_EMPTYTRASH=Trash:7,Sent:30 <– Enable automatic purging of mail from these folders
IMAPDSTART=YES <– allow our init.d script to boot up the imapd

#Lets start secure imap
vi /usr/local/courier-imap/etc/imapd-ssl
IMAPDSSLSTART=YES <– Enable secure IMAP
After enabling secure imap, PCI Approved Scanners
will fail your server if you dont set below line in
/usr/local/courier-imap/etc/courier-imap/imapd-ssl
IMAP_TLS_REQUIRED=1
TLS_PROTOCOL=SSL3 #(If server still fail the pci scan then change it to TLS1)

TLS_CERTFILE= <– Specify the SSL Certificate to use for secure imap

#Lets start secure pop
vi /usr/local/courier-imap/etc/pop3d-ssl
POP3DSSLSTART=YES
TLS_CERTFILE= <– specify ssl certificate to use for secure pop

Important: If you are using default
courier-imap package which is distributed with your OS distro then the
path to courier-imap files might be /etc/courier-imap/
