Howto: Renewing Exim SSL certificate
Renewing exim SSL certificate without using Cpanel or exim scripts,first we have to create the certificate and replace the file with suitable permissions, follow the below steps to do.
1, Creating Self signed certificate files using Openssl.
root@server09 [~]# openssl req -x509 -newkey rsa:1024 -keyout /root/server.key -out /root/server.crt -days 365 -nodes Generating a 1024 bit RSA private key ......................++++++ .............................................++++++ writing new private key to '/root/server.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [GB]:IN State or Province Name (full name) [Berkshire]:Karnataka Locality Name (eg, city) [Newbury]:Banglore Organization Name (eg, company) [My Company Ltd]:Private Ltd Organizational Unit Name (eg, section) []:JWH Common Name (eg, your name or your server's hostname) []:server.domain.com Email Address []:
2, Verify the existing location and filename and replace the files
root@server09 [~]# ll /etc/exim.key /etc/exim.crt lrwxrwxrwx 1 root root 31 2月 26 2010 /etc/exim.crt -> /var/cpanel/ssl/exim/myexim.crt lrwxrwxrwx 1 root root 31 2月 26 2010 /etc/exim.key -> /var/cpanel/ssl/exim/myexim.key mv /var/cpanel/ssl/exim/myexim.crt /var/cpanel/ssl/exim/myexim.crt_30_5_2013 mv /var/cpanel/ssl/exim/myexim.key /var/cpanel/ssl/exim/myexim.key_30_5_2013 mv /root/server.key /var/cpanel/ssl/exim/myexim.key mv /root/server.crt /var/cpanel/ssl/exim/myexim.crt chmod 660 /etc/exim.key /etc/exim.crt /var/cpanel/ssl/exim/myexim.key /var/cpanel/ssl/exim/myexim.crt chown mailnull.mail /etc/exim.key /etc/exim.crt /var/cpanel/ssl/exim/myexim.key /var/cpanel/ssl/exim/myexim.crt
3, Restart exim
root@server09 [~]# service exim restart
Error: exim logged Undefined subroutine &main::user2uid called. LOG: MAIN
My email server was not delivering any of the email from the domains hosted on my Cpanel server, I was checked the exim log, it shows some ACL (Access Control List)rules from the exim configuration. This will and also I tried to send email manually but the same error will logged. After googling for a minute I found the solution for this.
It is because for exim unable to read configuration characters. simple solution to fix this just rebuild configuration onceagain and copy exim.pl to /etc, now everythings looks fine
Exim error :
LOG: MAIN
cwd=/root 4 args: /usr/sbin/exim -i -v testemail@gmail.com
LOG: MAIN REJECT
F=<root@darkmatter.dnsprotect.com> rejected by non-SMTP ACL: failed to expand ACL string "${if eq{$originator_uid}{${perl{user2uid}{nobody}}}{1}{0}}": Undefined subroutine &main::user2uid called. LOG: MAIN
cwd=/var/spool/exim 8 args: /usr/sbin/exim -v -t -oem -oi -f <> -E1UY3r2-000
Rebuilding exim configuration:
root@server-web [~]# /scripts/buildeximconf Configuration file passes test! New configuration file was installed. /etc/exim.pl.local.build syntax OK Enabled system filter options: attachments|spam_rewrite .......... ... ........ /etc/exim.pl.local installed! razor2 is not installed, disabling it in SpamAssassin to save memory pyzor is not installed, disabling it in SpamAssassin to save memory SPF is disabled in exim or unavailable, enabling SPF for SpamAssassin Refreshing SMTP Mail protection.
Some it is necessary to copy the exim.pl to /etc, because the script will remove the file while rebuilding. check the file availability before executing this step.
root@server-web [~]# cp -rpf /etc/exim.pl.local /etc/exim.pl
Verify before restarting exim,
root@server-web [~]# mail -s "Testemail please ignore" "testemail@gmail.com" -- -f "testemail@example.com" Test email please ignore . Cc:
Hope this will help you.
