Mark, that reminds me...
I haven't tried this with imap-2006*, but in imap-2004g and earlier, this
didn't work for me. I wanted to use "sudo -u user mailutil ...", but
that doesn't work because my_username_full() in src/osdep/unix/env_unix.c
used getlogin() to get the username, then used that username to get the uid,
rather than just using getpwuid(geteuid()).
I patched this function locally so that we could use mailutil through sudo.
(I also just use pw->pw_dir rather than checking $HOME's status.)
Is there some other way that you recommend using mailutil while setuid'd to
the desired user? And is there some reason that my much simpler code is
likely to break that I haven't thought of, that justifies the more
complicated approach in the distribution?
