[bug-mailutils] using GSSAPI in /usr/bin/mail when connecting to an IMAP server?

[Daniel Kahn Gillmor]

Hi good people--

I'm having trouble finding documentation about using GSSAPI in GNU
mailutils.

in particular, the mailutils documentation says that the imap4d server
supports GSSAPI [0], but it doesn't mention whether mail (the MUA)
supports it as well.  It would be great if it did!

i have a functioning KRB5 domain with a GSSAPI-enabled (via SASL) IMAP
server (cyrus).  Other GSSAPI-capable MUAs (e.g. mutt) are capable of
using a krb5 credentials cache to connect properly to their mailbox
without additional authentication.  i'd like to set up /usr/bin/mail
to do this as well, if that's possible.

Can someone explain to me how i can coax /usr/bin/mail to select the
GSSAPI SASL authenticator instead of PLAIN or LOGIN?  A pointer to the
proper documentation would be great!

Thanks,

        --dkg
