NIS2009 Changed the email subject in Thunderbird.. and other things

Hello,

 

Yesterday I installed NIS 2009, and today, after checking my email in Thunderbird I notice that several message subjects now came changed. (the new messages subject)

 

Example of subject in messages before NIS2009:

- SomosCompatibles.com - ¡Tenemos una buena noticia para ti!

 

Now using NIS2009 the subject looks like this:

- =?ISO-8859-1?B?W05vcnRvbiBBbnRpU3BhbV0gU29tb3NDb21wYXRpYmxlcy5jb20gLSChVGVuZW1vcyB1bmEgYnVlbmEgbm90aWNpYSBwYXJhIHRpIQ=?=

 

It happened with at least 90 messages today.

 

Other thing is that a lot of messages now has the label [Norton AntiSpam] in the beginning. But there is no option for indicate that those messages are not spam!

 

I´m using Thunderbird 2.0.0.18 as my email client.

 

 

Thanks in advance

Gustavo
