Hi all,

we're using Version 8.11.6p2 on AIX 5.3.

The subject says what's the problem: When I send an e-mail via
/usr/bin/mail from an AIX-Partition to our internal mail relay, this
mail arrives with a sender address user@host.mydomain.de. We would like
to have user@mydomain.de, i.e. the hostname should not appear in the
sender address.

I'v tried compiling different settings in
/usr/samples/tcpip/sendmail/cf/aixsample.cf (MASQUERADE_AS, etc....)
with no success. Sendmail seems to be tooo complicated for me :-(

Any ideas? Thanks in advance!

Pete

OK try

http://www.sendmail.org/m4/masquerading_relaying.html

As you don't show us the relevant .mc file that is all we can do for now.

cheers

Hi Erich,

thanks, I was already poking around in the sendmail manuals.

IBM ships the file /usr/samples/tcpip/sendmail/cf/aixsample.mc with
AIX:

.....
# Sample AIX file
divert(0)dnl
OSTYPE(aixsample)dnl
FEATURE(genericstable)dnl
FEATURE(mailertable)dnl
FEATURE(virtusertable)dnl
FEATURE(domaintable)dnl
FEATURE(allmasquerade)dnl
FEATURE(promiscuous_relay)dnl
FEATURE(accept_unresolvable_domains)dnl
FEATURE(accept_unqualified_senders)dnl
FEATURE(no_default_msa)
DOMAIN(generic)dnl
define(`confSMTP_LOGIN_MSG', `$j Sendmail $b')
MAILER(local)dnl
MAILER(smtp)dnl
MAILER(uucp)

In the README they specify an exact order how to put things together
but MASQUERADE_AS or the other decalarations are not mentioned.

Which declaration(s) do I have to add and where?

Thanks

Pete

Yes I looked at it on an AIX 5.3, poorly documented, but there is always
sendmail.org

Not sure you need the allmasquerade

according to the sendmail docs something like the following

If you want to masquerade all hosts in the domain, use this feature

FEATURE(`masquerade_entire_domain')dnl

MASQUERADE_AS(`host.domain')dnl

should be enough to masquerade your host, if you need to masquerade more
hosts add

MASQUERADE_DOMAIN(`otherhost.domain')dnl

> FEATURE(promiscuous_relay)dnl

this one is dangerous, it opens up your MTA

.....

But then all this is explained at sendmail.org, a lot better than I
could ever do.

cheers

Hi,

just to clarify things: Sendmail on this partition doesn't act as an
MTA for other hosts. In fact, sendmail isn't running at all. I've seen
that it's started for a short moment when I run /usr/bin/mail. The AIX
partition is just an SMTP client and wants to send mails to our MTA
(MS-Exchange).

Of course I've checked sendmail.org but isn't that easy to understand
.....

My aixsample.mc looks like this now, but the MASQUERADE_AS option seems
not to have any effect:

# Sample AIX file
divert(0)dnl
OSTYPE(aixsample)dnl
FEATURE(genericstable)dnl
FEATURE(virtusertable)dnl
FEATURE(masquerade_entire_domain)dnl
FEATURE(masquerade_envelope)dnl
FEATURE(accept_unresolvable_domains)dnl
FEATURE(accept_unqualified_senders)dnl
FEATURE(no_default_msa)
MASQUERADE_AS(`mydomain.de')dnl
DOMAIN(generic)dnl
define(`confSMTP_LOGIN_MSG', `$j Sendmail $b')
MAILER(local)dnl
MAILER(smtp)dnl
MAILER(uucp)

When I send a mail on this partition I get the following (I changed our
real domain to mydomain.de ;-)):

root@aixutil: /etc/mail # mail -v -s Test user@mydomain.de < /dev/zero
Null message body; hope that's ok
user@mydomain.de... Connecting to mail.mydomain.de. via esmtp...

250 OK

Closing connection to mail.mydomain.de.
>>> QUIT
221 closing connection
root@host: /etc/mail #

In the EHLO and the Mail From lines we still have the host.... :-(

Any ideas? TIA

Pete

Edit /etc/sendmail.cf

Rule set 93 & 94 (masquerade)

Replace $j (host.domain) by $m (domain)

!!!Here under are these 2 Rule sets, I putted the modification between
double-quote("$m"). Don't put these double-quote but rather what they
contain!!!

compile sendmail.cf by the command: sendmail -bi

refresh -s sendmail

Hope this .

Hi,

many thanks, that works!!! I would have never been able to solve this
on my own.

Thanks again + kind regards

You did compile sendmail.cf from this and install it to /etc/mail?

cheers

Erich

I edited /etc/mail/sendmail.cf directly.

Suppose "sendmail -bi" wouldn't have been necessary, since according to
the man page this builds a new alias database from /etc/mail/aliases
and I didn't change any alias.

Regards

Pete

I got another solution from a ful guy.


See below the changes in my sendmail.cf on AIX 5.3:

.....
# who I masquerade as (null for no masquerading) (see also $=M)
DMmydomain
.....

# class E: names that should be exposed as from this host, even if we
masquerade
# class L: names that should be delivered locally, even if we have a
relay
# class M: domains that should be converted to $M
# class N: domains that should not be converted to $M
#CL root
#CE root

.....

################################################## #################
### Ruleset 94 -- convert envelope names to masqueraded form ###
################################################## #################

SMasqEnv=94
R$+ $@ $>MasqHdr $1
#R$* < @ *LOCAL* > $* $: $1 < @ $j . > $2

......

Of course if sendmail is running you have to refresh it:

refresh -s sendmail

It is generally frowned upon to hack the .cf file directly, because
migration tends to become a nightmare in the long run.

Erich

Maybe it's not the cleanest approach. But if you have two solutions by
doing it this way and zero solutions the other way, which one would you
prefer?

Thanks + kind regards

First, please visit: http://cfaj.freeshell.org/google/

Second, there are multiple solutions the "the other way", but the
specifically recommended/preferred one is to use MASQUERADE_AS(). The
most likely reason it didn't work for you is that a) you were sending
mail as root (never a good idea), and b) your .mc file had the line

DOMAIN(generic)dnl

which says to include the file cf/domain/generic.m4, which at least in
the original sendmail distribution has the line

EXPOSED_USER(`root')
