If you have problems with an exim + MailScanner config where emails get into your system but then they get stuck on queue and not delivered to final destination (incoming exim works but the one that sends email to the outside world after MailScanner does not) be sure to check the file /etc/exim/trusted-configs

Inside this file you must specify the two config files that MailScanner should use. For example:

Effects of radiation exposure

Category: ciencia,Curiosidadesguillem @ 12:45 AM

With all the news that has lately followed the Japan nuclear plants incident I think it is really important to be as informed as possible about the subject.

Tha diagram is from an Andrew Barr article’s at the National Post. You will also find there a really interesting source of updated information about the incident:
