How about a compromise like, creating a second set of home directories
on the mail server (which will contain the .forward files only).  This
way, mail is delivered as usual, forwarding works instantly, and if a
user does anything fancy in his .forward file, then it is the problem
if the programs/shell scripts he starts in there to ensure that they
deliver the mail or not (e.g. EX_TEMPFAIL).

This way the users do not have to log in to the central server to read their
mail, only if they would want to change their .forward files.  And, best
of all, it works without having the source of sendmail.

Subject: sendmail from address rewriting question ..

Followup-To: comp.mail.sendmail
Organization: University of Pennsylvania

I am by no means a sendmail expert and am seeking advice on a particular
configuration I would like to achieve:

I have 3 (NeXT) machines on a network, with home directory space and
/usr/spool/mail shared off the server machine. Let us say the machines
are called: server, client1, client2

I want to have the server be the mailhost. Now, one user always uses
client1 and would like to have his/her mail go out with the 'From'
line as:

From user1@client1

For all the other users, mail will go out with from line:

From user@server

Thus my question is: can sendmail be configured to operate in such a way.
More generally: can sendmail be configured such that the sender address
rewriting occurs on a per user basis?

If sendmail cannot do this, are there any other more sophisticated MTA's
that can do this job?

thanks,

I had forgotten about the queue.  (a) is definitely better then....

Why is that clients should directly deliver?  Is it a server loading
issue?  To me, it seemed like just having all clients dump to the
server was better because then you only had one real point on the
net to worry about (w.r.t sendmail...)

I looked through those; I just wish they were commented a little
more heavily (considering my newbie status with sendmail-type issues).
I guess some experimentation is in order....

Sendmail.cf can indeed be configured to do this but why bother?  The user
him/herself can add a From: line to mail indicating whatever they want.  IE,
if they insert a From: line like

	From: theirlognam@dco.dec.com

even if they were on

	theirlognam@att.com

the inserted From: would go out as they write it.

Many Mail User Agents allow you to add a From: line.

Is there a way to limit the number of simultaneous outgoing
sendmail connections to the same address during a queue run?

Very often our mail-relay receives a large number (hundreds) 
of mail messages with identical receipient addresses. During a 
queue run the number of simultaneous sendmail processes connected
to that address and hanging in the "DATA wait" state grows sometimes
up to 150. This does't harm our mail-relay, but could drag down 
the receipient host on the other end of the - usually low bandwith -
line.

If you just want to send everything to your server (with IDA sendmail),
you might want to try mp.cs.niu.edu:/pub/cf/simple.cf .
It is technically experimental, but I think it is pretty reliable.  In any
case it is so simple, there isn't room for it to have many bugs.

In the interests of keeping my kneecaps, I'd like to add to John Haxby
(Definitively Wrong)'s comments.  I do not truncate long headers; I move
them to the end of the body and replace the header with a placeholder
that looks more or less like

	To: distribution:; (see end of body)

which is syntactically valid and semantically nil as far as sendmail goes.
Given this solution, headers can be of any length less than the number of
bytes free on your file system, which is probably enough but I'd be willing
to listen to (creative) reasons why this is still too short.

Berkeley removed the 2500-character limit as of 5.65 or so, but old sendmails
will still dump core when processing mail with headers longer than 2500 bytes,
which is why I chose the solution I did.

All this is in gatekeeper.dec.com:~ftp/pub/misc/vixie/kjs.tar.Z, as always.

This is a configuration problem.  You apparently are not using a config
file built with the your IDA package in subdirectory ida/cf

The error occurs when your mailer has the 'U' flag defined in the "F="
string of flags, but the sender address does not contain a '!'.  Note
that this is the envelope sender address after processing by ruleset
3,1, the mailer S= rule, and 4.  Time to check on your rewrite rules.
Or just build an IDA config file, and save yourself the trouble.

Subject: IDA-sendmail: NIS vs. DNS name lookup
Summary: I want to use both (and MX records)
Date: 18 Aug 92 15:58:48 GMT
Organization: Georgia Tech Research Institute

Yet another IDA-sendmail set up question.  On a network of Suns, I want
a main mailhost and client machines.  Currently I run NIS on the
network for host lookups.  The NIS server maps were made with the -b
option so that name lookups that fail at the local NIS level will then
be handed to DNS.  The NIS master server has a /etc/resolv.conf file
that points to the DNS machine (not under my control).  The result
works, from any client I can ping/telnet/etc. a host; if "local" then
it works (via NIS), if not local it still works (via NIS handing off to
DNS).  I like this hand off scheme because my access to the name server
is not perfectly reliable and this way my hosts can communicate among
themselves even when the DNS machine is down.

So now I compile IDA-sendmail with DNS/BIND stuff built in.  The client
I test on does not have a resolv.conf file and thus name lookups won't
work.  Should I take the DNS stuff out (thus allowing name lookups
using NIS)?  If I do this will I lose the ability to deliver to MX
records (which I am required to do)?  How can I get the best of both
worlds?

Thanks for any pointers,
Robert

You either want to keep the daemon running on the clients or have periodic
invocations of sendmail -q from cron to move items stuck in the queue.
The clients should deliver directly whenever possible and bypass the
server.  All that needs to be done is to re-write the From: address to
be user@domain.name.

If you have a shared mail spool exported from the server, then all local
deliveries should take place on the server.

If you look in the sendmail source directory on uxc.cso.uiuc.edu in
mail/sendmail/ida/cf/M4 you'll find several sample M4 files for sundry
configurations similar to what you want to do.
