in case of external auth no passwords are stored anywhere.
it just checks for the correctness of the given username/password.

in case of external prefs (customizable with external auth also), also 
the other prefs are not stored in any page or cookie.

in case of loose PagePermissions and homepage stored prefs one could 
look at prefs of other users, with the metadata viewer plugin.

PHPWiki runs well over an HTTPS connection, if the images are also on 
HTTPS (no external img src). otherwise you get lot of warnings.

I never did an IMAP connection over a secured connection (SSL, TLS, ...) 
yet. imap_open does support TLS/SSL if compiled against OpenSSL.
stunnel is the other possibility:
  see http://security.fi.infn.it/tools/stunnel/index-en.html
If this is not possible or the imap server does not support TLS/SSL, the 
given password is passed cleartext to the IMAP server (AUTH=PLAIN), same 
as with every unsecured mail client connection.

in other projects of mine. in my tep addons (oscommerce.org) for 
example. not in phpwiki yet.
