=== SSL on courier and qmail ===
This is extremely raw. Will clean this up when I get around to it.

==SSL and courier==
1) Generate a self-signed certificate
%%
openssl genrsa -des3 -out server.key 2048
openssl rsa -in server.key -out server.key.plain
openssl req -new -x509 -key server.key -out server.crt -days 360 -set_serial 200711
%%

2) Make a pem file
%%
cat server.key.plain server.crt > server.pem
openssl gendh >> server.pem
chmod 400 server.*
%%

3) Edit imapd-ssl / pop3d-ssl file
TLS_CERTFILE=/path/to/server.pem
START=YES

4) Start imapd-ssl and pop3d-ssl

5) Verify with openssl
%%
openssl s_client -connect localhost:993
openssl s_client -connect localhost:995
%%

==SSL and qmail==
1) Get ucspi-ssl http://www.superscript.com/ucspi-ssl/ucspi-ssl-0.70.tar.gz
2) Get ucspo-tls patch http://www.suspectclass.com/~sgifford/ucspi-tls/files/ucspi-ssl-0.70-ucspitls-0.1.patch
3) Extract ucspi-ssl and patch it
tar zxf xxx.tar.gz
patch -p1 < ../ucspi-ssl-0.70-ucspitls-0.1.patch
4) Compile and install it
	package/compile base
	package/install base
5) Patch netqmail 
netqmail-1.06: http://www.qmail.org/netqmail-1.06.tar.gz
netqmail-tls patch: http://www.suspectclass.com/~sgifford/ucspi-tls/files/netqmail-1.05-ucspitls-0.3.patch 
%%
patch -p2 < ../netqmail-1.05-ucspitls-0.3.patch
%%

6) Create qmailssl user
groupadd qmailssl
useradd -g qmailssl -d /var/qmail qmailssl

7) Create /var/qmail/ssl/env
%%
SSL_USER=qmailssl
SSL_GROUP=qmailssl
SSL_DIR=/var/qmail/ssl
# Enable UCSPI-TLS
UCSPITLS=1
# The rest are set based on the above three
SSL_CHROOT="$SSL_DIR"
CERTFILE="$SSL_DIR/cert"
KEYFILE="$SSL_DIR/key"
DHFILE="$SSL_DIR/dhparam"
SSL_UID=`id -u "$SSL_USER"`
if [ $? -ne 0 ]; then echo "No such user '$SSL_USER'" >&2; exit; fi
SSL_GID=`id -g "$SSL_GROUP"`
if [ $? -ne 0 ]; then echo "No such group '$SSL_GROUP'" >&2; exit; fi
# Export the variables used by other scripts
export SSL_CHROOT SSL_UID SSL_GID UCSPITLS CERTFILE KEYFILE DHFILE
%%

8) Copy /var/qmail/supervise/qmail-smtpd to qmail-smtpd-ssl and edit the run file inside
8.1) add . /var/qmail/ssl/env to the top
8.2) replace tcpserver with sslserver -e -n
8.3) Change smtp to 587 if you wish to run smtp on port25, and smtps on port587
8.4) Generate certificate in /var/qmail/ssl
	umask 077
	openssl req -new -x509 -keyout key.enc -out cert -days 360
	openssl rsa -in key.enc -out key
	openssl dhparam -out dhparam 1024
	umask 022
8.5) Start qmail
