[bug-mailutils] figuring out mailuils...

[Alfred M. Szmidt]

I'm trying to add some more error checking, and general paranoid
behaviour to movemail, but I am not even sure where to begin to add
this...

I am finding the documentation a bit lacking over what each function
does, specially on a protocol basis.  Does for example
mu_mailbox_get_message remove messages when fetching from a POP3
server?  Does mu_attribute_set_deleted touched all messages when doing
POP3?

Is there some simple overview of how the protocol side is implemented?

Where would the best place be to add some kind of a UIDL list (if a
server supports it)--not file location, but codewise--of messages
retrived, so one doesn't fetch duplicate messages?
