discussion on nmap-dev about how best to handle these. I also updated the docs and
am about to regenerate script.db. See this thread for more info:
http://seclists.org/nmap-dev/2009/q3/1008.html
The imap-capabilities script is mostly feature-complete but I could
see adding some analysis code to warn users of non-SSL'd IMAP servers
that offer STARTTLS without NOLOGIN.
The imap "library" is really a joke. It does the minimum required to
support getting capabilities and nothing more. IMAP requires each
command to use a unique identifier like 000, 001, 002, etc. Right now
the identifier is hardcoded to a001. To make a real imap library that
supports logging in, and other IMAP features a state variable will
have to be maintained to change the command uid. It would be nice to
see the library get updated so that IMAP brute-forcing could be
supported.
