Re: pop3: avoid fetching a mail twice

Can I assume from this response that the mailmap_* functions also do no
caching?  They are just low-level functions that fetch information from the
IMAP server?  I loved libEtPan before, but now I think it is the best thing
since sliced bread.  This is exactly what I was needing.  I have wanted to
handle the caching myself in my application, but I thought I was going to
have to live with the fact that both libEtPan and my app would retain
caches.  These low-level functions are *exactly* what I needed.  Thanks for
such a well-designed library.
