Depending on how large the mailbox is, you may see timeouts under certain conditions if something (e.g., procmail) is trying to deliver to an mbox while mutt has a lock on it. I experienced that problem recently. So, if you're delivering directly to the large mbox in question, I'd just make sure that anything / everything that may be delivering to it has a long timeout setting. I use a mix of Mbox and Maildir on both of the systems I read mail on. Obviously, there are certain cases where lots of small files is less efficient than one big file, or vice-versa, and some of this may also depend on your filesystem. But I have found situations where Maildir + header caching does certain types of things more efficiently than with mbox. w
