Email archiving Software for multiple email accounts

[Chrisjmv]

I am looking for a software for MacOS to archive multiple email accounts with up to 50.000 emails automatically and to search attachments in seconds.
Thereby different eMail accounts like google, microsoft etc. should be integrated.

Who knows such a program that can do this?

Try EagleFiler $49.99 at c-command.com Seems to be optimized for email archiving.
