Things to know about ELM:

do "add mime" (for /mit/mime/decmipsbin or whatever)

Where is yet-to-be-read mail spooled? [/usr/spool/mail] ~/Mail/inbox

Mail group is system

Elm needs to be installed and run as a setgid program only if the mail
spool directory permissions do not allow world write access.  If your
mail spool directory has the permissions:

drwxrwxr-x  3 root     mail          512 Dec 24 17:20 /usr/mail

then Elm must be setgid to the same group as the mail spool directory
(in this case group mail).  However, if the spool permissions look
like:

drwxrwsrwt  2 root     staff         512 Dec 21 20:14 /usr/spool/mail

then Elm should not be installed or run as a setgid program.

Am I going to be running as a setgid program? [y] n

(This might need to be changed.)

I will not be keeping anything in MH format.
I will have two conversions:
...here's basically what'd happen:

1) inc
2) convert number files in ~/Mail/inbox into an ELM folder
3) delete the number files

Now the Mh files are gone.  So now you can manipulate your mail happily.
When you send something, the following would happen:

1) create the message (which ELM already puts into a /tmp file)
2) instead of sending it normally, have it issue a "send /tmp/123.snd"
command (with whatever .snd file it created)
3) Before sending, we'd put in the proper headers, of course.

*** HESIOD ***

you query the hesiod database.
it's fairly simple.  source for hesinfo is:
attach source; cd /source ; look hesinfo FILES.look

hesiod is what you want.
there's no way to get anything else.
do what I sent to look at the hesinfo source.
there's a short document on programming with hesiod - it should be in there.
(it's simple)

also you can look at /mit/consult/src/hes/hes.c for a short example of a probram that
uses the hesiod libraries...

do something like:
hes_resolve(username, "passwd")

(in c code that is)... that will give you the password entry...  then do some
sscanf on it

**** POP ****

ok..
probably the best thing to do first is run the `pop' command, in the sipb locker

*** Patch for SENDING MAIL ***


I.	mailmsg2.c

	write_header_info

	(username is user@machine)
	at beginning of procedure
	find "@" in username
	set that to \0
	...
	at end of procedure
	make the \0 at the end of username equal to "@"


II.	Use the code for /usr/athena/bin/send to create a mail-sending thing
