[For the impatient: I want mail to either be sent from my school's smtp
server, or to look like it's been sent from my school's smtp server. I
don't want people to see things like my home IP in my mail
headers. I'm using mutt, which doesn't have a built-in MTA.]
Normally I send mail through my school's smtp server. Now I'm trying
out mutt which by all accounts needs a separate MTA. That's OK, I
guess (**grumble**), I've got sendmail. So I'm now sending mail with
sendmail. Here's some logs (this is the sendmail that comes with
whatever yesterday's stable version was):
Oct 14 08:49:17 localhost sendmail[18389]: starting daemon (8.9.3):
[EMAIL PROTECTED]:10:00
Oct 14 09:02:21 localhost sendmail[18627]: JAA18627: from=krzys,
size=298, class=0, pri=30298, nrcpts=1,
msgid=<[EMAIL PROTECTED]>, [EMAIL PROTECTED]
Oct 14 09:02:22 localhost sendmail[18629]: JAA18627:

xdelay=00:00:01, mailer=relay, relay=smtp.cs.ubc.ca. [142.103.6.52],
stat=Sent (JAA23848 Message accepted for delivery)
OK, so it works. Here's my problem. Looking at the mail headers (via
'less $MAIL' on the school server), I see the following:
>From [EMAIL PROTECTED] Sat Oct 14 09:02:22 2000

Compare this to the headers I get when sending from school:

See? Much nicer! In particular, I take issue with the
following headers. Either I don't want the whole world to see them (eg
my IP address) or I'm not sure if they're necessary or even correct.
>From [EMAIL PROTECTED] Sat Oct 14 09:02:22 2000
Nobody has to know about krzys.com.
I want people to think my mail is coming from cs.ubc.ca.
Ideally I want the mail to actually come from cs.ubc.ca, as it was
before. I'm not trying to scam anybody here, I just want my mail
system to be as separate from my desktop box as possible (like it was
before I started using mutt)

OK this is a problem. I don't want the world to see things like
[EMAIL PROTECTED] or my IP address.
And what's the deal with "from localhost.cs.ubc.ca", is that even correct?
Received: (from [EMAIL PROTECTED])
Don't like this [EMAIL PROTECTED] business, what's up with that?

Still not convinced about localhost.cs.ubc.ca.
There it is. Oh yeah, a putative solution should not break the ability
of cron jobs etc. to send mail to me, via .forward (or some other mechanism
if necessary) to my usual (school) mail account.
