Thanks for this

Yes I am trying to reformat email archives that have been output from a 
lyris mail server, and have already gone through many transformations on 
both unix and windoze servers. It has become a messy situation with an 
early version of lyris creating a txt archive but unable to parse its own 
imput when importing them back. I have found a format that Lyris likes and 
am trying to reformat them to suit it. Due to research being conducted on 
the archives, they need to be re-instated and lyris have been unable to 
provide a solution to date

Cheers
Shaun
