If you use virtual_mailbox_limit with strictly maildir mailboxes, you
may as well set message_size_limit=0 and leave it alone, so you only
have one setting to keep track of.
BTW, I can't see the logic in ever increasing the default, which is
~50MB. Do your users ever receive single 50MB emails? Do you want them
receiving 50MB emails? If anything you should probably lower this
value, not increase it, unless this is a special purpose server that
regularly receives large CAD drawings or Photoshop images or the like.
