That's the way mbox format works. One IMAP or POP3 client can lock the mailbox for a long time. LDA can either wait longer of fail and let MTA retry the delivery later. The default is: mbox_lock_timeout = 5 mins So apparently the LDA already waited for 5 minutes for the lock. (There is also actually mail_max_lock_timeout setting, but the default is 0 = disabled.)
