[Alpine-info] folders and certificate placement?

[Karen Lewellen]

Hi all,
One of the members of the greater Toronto Linux users group is creating an 
email  account on their personal email servers.
They have never used alpine before, asking me a couple of questions.
since Imap is going to be involved, what setting tells alpine to place say 
the sent mail folder there, or anywhere?
Ron is asking about certificate placement too, they are good, but again 
alpine is unhappy with them, perhaps another placement issue?
are there things that cannot be set from the settings area of the main 
menu, needing a config?
If so, what is it called?
Thanks,
Karen
