Howto consume message from unix mailbox

[Bernard Delmée]

Hi,

I am retrieving messages with the mailbox module and 
processing them with the email module. Now there 
doesn't seem to be support in the library to actually 
remove the read messages from the mailbox.

Am I overlooking sthg from the stdlib, or is any 
third-party code available to actually modify the mbox
file safely (locking, concurrent access by a delivery
mechanism...)?

Thanks,

Bernard.
