* Creat TLS/SSL certificates at install time (4.63-6)
See below.

* New If enabled, Exim support authentificator using saslauthd with
  cyrus-sasl (4.63-6)

Feature disabled with exim-4.63-7mdv2007.
All parameters are documented into /usr/share/doc/cyrus-sasl-2.*/options.html
and /etc/sasl2/smtpd.conf .To use Exim with cyrus-sasl authentificator, in the
authenticators section below, there are template configurations for plaintext
username/password authentication.

You can rebuild to enable/disable saslhautd option:
rpm --rebuild --define "_with[out]_sasl2 1[0]"
%{name}-%{version}-%{release}.src.rpm

* Now Exim use logrotate (4.63-6)
Cron job with exicyclog as disabled. If exist /etc/cron.weekly/exim as
moved to /etc/exim/cron.weekly_exim.backup.$day
You can rebuild to enable/disable logrotate option:
rpm --rebuild --define "_with[out]_logrotate 1[0]"
%{name}-%{version}-%{release}.src.rpm

* New adding embledded perl script (4.63-6)
Adding method using EXIM's embedded perl to authentificat users with
POP3 or IMAP accompt. You have to load a perl program at start time
and then it makes calls to a perl subroutine. The Perl routine
attempts the IMAP or POP3 login and returns the result to Exim.
In order to make this work you must first load in MAIN CONFIGURATION
/etc/exim/conf:
perl_startup = do '/etc/exim/exim_perl.pl'
perl_at_start

* New eximstats send report via mail to postmaster (4.63-6)
You can enable/disable send report in /etc/sysconfig/exim: (enabled)
EXIM_REPORT_WEEKLY_SEND=yes/no

* New eximstats create HTML report in /var/www/eximstats/$day (4.63-6)
You can enable/disable create HTML report in /etc/sysconfig/exim: (disabled)
EXIM_REPORT_WEEKLY_HTML=yes/no

Adding alias directorie (/eximstats /var/www/eximstats) for apache in
/etc/httpd/conf.d/eximstats.conf (4.63-7)

* New Exim support lookups in SQLite3 database (4.60-0-1.20060sd3l)
SQLite is different to the other SQL lookups because a file name is
required in addition to the SQL query. An SQLite database is a single
file, and there is no daemon as in the other SQL databases.
The interface to Exim requires the name of the file, as an absolute path,
to be given at the start of the query. It is separated from the query
by white space.
This means that the path name cannot contain white space. Here is a
lookup expansion example:
${lookup sqlite {/path/sqlitedb SELECT name FROM aliases WHERE id='userx';}}

In a list, the syntax is similar. For example:
domainlist relay_domains = sqlite;/path/sqlitedb SELECT * FROM relays \
WHERE ip='\${quote_sqlite:$sender_host_address}';

The only character affected by the quote_sqlite operator is a single
quote, which it doubles.

You can rebuild to enable/disable sqlite3 option:
rpm --rebuild --define "_with[out]_sqlite3 1[0]"
%{name}-%{version}-%{release}.src.rpm

* Useful commands on command line:
"exim -bpc" : View the list of messages in the queue
"exim -Mvb" : View for a detailed message its body
"exim -Mvh" :View for a detailed message its headers
"exim -d+expand -be" : DEBUG PROCESS AND MAILBOX
"exim -bd -d -oX 25" : DEBUG FOREGROUND WITH FIXED LISTENING PORT
"exim -bd -d -q15m" : DEBUG FOREGROUND
"exim -bp | awk '{print $3}' | xargs exim -v -M"  : UnFreeze messages
"exim -bp | awk '{print $3}' | xargs exim -v -Mrm" : Delete queued
messages

############# IMPORTANT ############ IMPORTANT #############
Whenever you change Exim's configuration file, you *must* remember to
HUP the Exim daemon, because it will not pick up the new configuration
until you do. However, any other Exim processes that are started, for
example, a process started by an MUA in order to send a message, will
see the new configuration as soon as it is in place.
You do not need to HUP the daemon for changes in auxiliary files that
are referenced from this file. They are read every time they are used.
It is usually a good idea to test a new configuration for syntactic
correctness before installing it (for example, by running the command
"exim -C /config/file.new -bV"

* TLS/SSL:
You can create TLS/SSL certificates:
openssl req -x509 -newkey rsa:1024 \
   -keyout /etc/pki/tls/private/exim.pem \
   -out /etc/pki/tls/certs/exim.pem \
   -days 365 -nodes

openssl dhparam -check -text -5 512 \
   -out /etc/pki/tls/dhparam/exim.pem

tls_certificate = /etc/pki/tls/certs/exim.pem
tls_privatekey = /etc/pki/tls/private/exim.pem
tls_dhparam = /etc/pki/tls/dhparam/exim.pem
tls_advertise_hosts = *

daemon_smtp_ports = 25 : 465 : 587
tls_on_connect_ports = 465
#auth_advertise_hosts = ${if eq{$tls_cipher}{}{}{*}}
