Après vérification:
mailbox_size_limit (default: 51200000)
The maximal size of any local(8) individual mailbox or maildir file, or zero (no limit). In fact, this limits the size of any file that is written to upon local delivery, including files written by external commands that are executed by the local(8) delivery agent.
This limit must not be smaller than the message size limit.
Donc ton problème je pense vient bien de ce paramètre ...
