What file system are you using? The 2GB limit doesn't sound like anything related to Postfix (unless you set Postfix's mailbox_size_limit directive years ago then forgot about it).
(There's also another discussion about whether it's worth the time and trouble to run your own mail server these days, when outsourced email is cheap and often free, but most of the people on this list probably would run their own stuff regardless, for the fun or the experience.) Does your "old" mail system support POP, or only local access? Somewhere around here, I've got a script I wrote years ago for doing bulk moves between mail servers, but it requires at least POP (and ideally IMAP) access to the source server. For that matter, if both source and destination are network-accessible you can just use something like MigrationWiz; it's well worth the ten bucks or so per mailbox.

I've been running Postfix as a mail server for many years, it's currently running on a CentOS 5 system. I've also been using pine (or alpine) to read my email for decades. Well, it appears that Postfix may have a maximum limit of 2G on mailbox size and I'm bumping up against it. The system itelf has a 1T disk with lots for ree space. So, I need to overhaul how I handle email (something I've been meaning to to for years now). I would like to convert to an IMAP style mail handling so I can use something like Thunderbird for writing ad-hoc mail sorting. Currently the mailbox and all the "folders" that things are saved in are in mbox format. That should probably change to Maildir. This server has been so stable for so many years that I've forgotten most of what I learned about mail servers since I set it up. So, I really need some help in figuring out which way to go and how to get there. Pointers to good documentation appreciated. I also understand if you want to scold me for such laxity, but "the cobbler's children have no shoes" -- Matt It's not what I know that counts. It's what I can remember in time to use. _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/ _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
