This tends to be implementation dependant as much as format related. Though many people consider MH as obsolete, I would consider it as an intermediate format. It will read the maildir file and split it into it's own MH format which uses single files. Even though it can be slow, the nice thing about mh is that it is all command line based and it's easy to write shell scripts, to move and sort messages. Also it tends not to crash. Evolution does read mh format (thunderbird does NOT), and I have used it to move 200mb mh folders into a dovecot server using maildir. I think the key here is to split into smaller folders (maybe even less than 200), even if you put it back into one at the end, that way your less likely to get bitten by evolution crashing 3/4 of the way through. If you get it into 4 folders in dovecot, I believe you can just rename (mv) the files directly on the server (I think the file names are unique) into one folder and reindex the folder. Also, the UW imap server reads mh format, but I have never used it and have no idea what its performance is like.
