Saving emails från


I have over 3.800 bounced emails in and want to save them in one file, and then use MailExtractor to extract the bounced emails.

The thing is that I have tried to save the both from Save as / Plain text and the MailScripts Archive messages.

Now,, MailScripts crashes after 1-2 hours and Save as have been working for 8 hours now. Some thing wrong? Is there a better way or application?
