Hi folks,
Exim 3.33 is now up and running on the server and has been found to be stable enough to go live :) If you experience any problems with the lists over the next couple of days, please drop me a note and I will try and fix things as quickly as I can.
Regards,
Martyn
PS. The only dislike I have about Exim is that in order for anybody to authenticate through SMTP AUTH with /etc/shadow support, you're going to need to use the pam_exim module available from http://www.e-admin.de/pam_exim/ as this is the only "secure" thing that will work other than to run exim as root.
