If anyone can help with this I'd appreciate it. I'm trying to set up a
small intranet server, and want to send email out via PHP's mail command
and sendmail.

Now, in PINE and PHP, the system has set my sender email address to
"linuxuser@webserver.ourcompany.com". This results in some mailservers
dropping mail from our machine as "webserver.ourcompany.com" doesn't
resolve. The exact error message is "(reason: 550
<linuxuser@webserver.ourcompany.com>: Sender address rejected: Domain
not found)"

I guess I've made a configuration boo-boo when I set the box up, here's
what I have:

hostname = webserver
domainname = ourcompany.com
dnsdomainname = ourcompany.com

How do I configure my system so that the sender address is
"linuxuser@ourcompany.com" rather than it inserting the hostname in the
Sender: part? I'd prefer to do this at the system level rather than
modifying the Sender: address in each and every application I use.
(I've no idea if the error I'm making is a Slackware one, or a Sendmail
one).

Just a note: The intranet server is behind a firewall, our domain
'ourcompany.com' is valid, but the subdomain 'webserver.ourcompany.com'
is not. That's simply what we've called the system on our internal
network. Is it at this point I'm going wrong, and should I call it
something else internally?

Thanks in advance

In your sendmail.mc file put a masquerade line in:

MASQUERADE_AS(`ourcompany.com')dnl

After that re-generate your sendmail.cf file, put it in /etc/mail and
restart sendmail (# /etc/rc.d/rc.sendmail restart). That will make
whoever@whatever.ourcompany.com be changed to whoever@ourcompany.com.

Hope this helps.

Hi Greg,

It sounds like that's what I need to do, I thought it might have
something to do with the way I'd configured 'hostname', 'domainname' etc
when I installed.

I've done a 'slocate -u' to update my file list, and 'slocate
sendmail.mc' but I don't appear to have this file, so I'm not sure how
to rebuild my sendmail.conf. Is hunting down a copy of sendmail.mc my
best bet then trying what you've suggested, or is it possible just to
modify my sendmail.conf directly?

Thanks,

Adam.

Okay, so I did this:

1. cd /usr/share/sendmail/cf/cf
2. cp sendmail-slackware.mc newsendmailconf.mc
3. [edited newsendmailconf.mc adding the MASQUERADE_AS line]
4. m4 newsendmailconf.mc > /etc/mail/sendmail.cf
5. [rebooted rather than restarting sendmail, just to be on the safe
side ]

Now my /etc/sendmail.cf has a new line in:

DMourcompany.com

However, I'm still having the same problem. Outbound mail is still
stamped '@hostname.ourcompany.com' rather than just '@ourcompany.com'.
Can anyone offer any advice on how to fix it?

Cheers

Look in Sendmail-Address-Rewrite in the mini-Howto directory and it
will tell you what you need to know.

cordially, as always,

rm

Holy shit, after 8 hours it's working!

Thanks for the response rm, I didn't have any luck with that
unfortunately. I think that's to do with routing mail addressed locally
to external addresses.

However, after Greg's suggestion earlier I've modified my
'newsendmailconf.mc' I created earlier but added a few more lines:

MASQUERADE_AS(`ourcompany.com')dnl
MASQUERADE_DOMAIN(`ourcompany.com')dnl
FEATURE(`allmasquerade')dnl
FEATURE(`masquerade_envelope')dnl

Thanks for the pointer Greg

If your running slackware 9 and also the default sendmail config out of it
then use:

/usr/share/sendmail/cf/cf/sendmail-slackware.mc

This is the default sendmail configuration for slackware. You can change
to that directory and edit the file directly and then use make to generate
your cf file.

# cd /usr/share/sendmail/cf/cf
# vim sendmail-slackware.mc
# make sendmail-slackware.cf
# cp sendmail-slackware.cf /etc/mail/sendmail.cf

You can replace vim with your favorite editor. Since it seems your new to
sendmail configuration I would like to point out the quoting above in the
mc directive. That is a back-quote followed by a normal quote `'. It will
make a difference

Again, hope this helps.

Hello,

I think the Return-Path of your e-mail is set to
something@webserver.ourcompany.com. There are 2 ways to get rid of this
problem:

- Workaround: change your Return-Path of the e-mail you send.
- Fix: configure sendmail to masquerade as ourcompany.com instead of
webserver.ourcompany.com, especially if you are sending e-mail to the
Internet.

Regards,

Tristan

Heh, sure

Seems having a slow dial-up with a news server that synchronizes only once an
hour (if the last synchronization has completed) makes for poor response
time. I'm glad you figured it out, and disregard the last reply (which
obviously has arrived after this post).
