Sorry, that was supposed to read “100,000,” not “10,000.”Well... the free version may be limited, but the middle version can handle 50,000 using SQLite, and the MailSteward Pro version (MSP), which uses mySQL, can handle millions.
I tried to use MSPro but could never get it set up. It would have been great to do what you do. I got little or no help and gave up on it. I'm sure others can get it to work.
My first archive collection has 120,000 emails plus their attachments, and I started a new one this year. My mail volume is higher than most people's, because I used to operate a popular and wide-ranging web site.
