[Mailman-Users] Locking mailbox files

[Rowan Sylvester-Bradley]

Hi,

Does Mailman need to lock Mailbox files? If so, how does it do so?

My hosting company runs Mailman. I'm writing a script which modifies my
mailbox files to delete old messages, and I need to be able to lock the
files before I do so to stop any other process from trying to modify
them at the same time. The way that Mailman does this may give me a clue
how to do it...

Thanks - Rowan
