The messages are never split into multiple files. So if you have a 20 MB message, it gets stored into its own m.* file.
Should I tune it (at least mdbox_rotate_size and mdbox_rotate_interval) or its size is on purpose? As for now I store each day's messages in separate IMAP folders (mailboxes), which gives me 2000-6000 messages and 2-5 Gb (on disk) per folder.
The main problem with larger mdbox files is that if you expunge messages, there's more data to write when packing the data into a new file. I don't really know the "best" value for mdbox_rotate_size setting. But even a 2 MB mdbox file can contain thousands of small mails, so it's not too bad..
