downgrade to netscape 4.78

[Herbert Reischl]

Hi,

I have several problems with netscape 6.1 in the german language. fonts, 
browsing, ....
I give up ... :-(((

I was very lucky with netscape 4.78 and now I want to downgrade. The old 
email-file format was .snm.
The new email-file-format is .msf

Is there any possibility to convert the .msf-files into .snm?  

Or what is the easiest way to move my stored mails to my lovely netscape 
4.78?

Many thanx in advance!
Herbert
