sendmail configuration (getting rid of localhost)

[patrick99e99]

Hi,

I was just curious, can anyone help me configure my sendmail so that when I send mail from the commandline it does not show up from localhost? ISPs like aol automatically block all of my mail...

I am using mac os x 10.4, and I currently have my computer online accessable as a subdomain to my regular domain.

Edit your sendmail.mc and add

MASQUERADE_AS(`[b]qualifieddomain.com[/b]')dnl
FEATURE(`masquerade_envelope')dnl

Then use m4 to rebuild the sendmail.cf

% m4 /path/to/sendmail.mc > /path/to/sendmail.cf

Hmm.. I have searched my entire computer and I somehow do not have a .mc or .cf file...

rufus[patrick] /> sudo find /. -name sendmail*
/./Applications/Macromedia Dreamweaver MX/Configuration/TagLibraries/JRun/sendmail.htm
/./Applications/Macromedia Dreamweaver MX/Configuration/TagLibraries/JRun/sendmail.vtm
/./System/Library/Perl/Extras/5.8.6/Mail/Mailer/sendmail.pm
/./usr/lib/php/Mail/sendmail.php
/./usr/sbin/sendmail
/./usr/share/emacs/21.2/lisp/mail/sendmail.el
/./usr/share/emacs/21.2/lisp/mail/sendmail.elc
/./usr/share/man/man1/sendmail.1
rufus[patrick] />

any suggestions?

Have you looked in the /etc/mail directory? Keep looking, it has to be somewhere. Sendmail needs at least the sendmail.cf file.

 

[patrick99e99]

I actually have no mail directory in /etc...

is this a problem?

[mbrooks]

On the command line do

% whereis sendmail

If this fails to find anything then you are not using Sendmail as an MTA.

rufus[patrick] ~> whereis sendmail
/usr/sbin/sendmail

but I looked there are no directories there.. only executable programs and symbolic links.

What flavor of linux are you running. A lot of times you can go to the distributor's website and find what you need in their FAQs or forums. Another thing you might try is look in /usr/share/sendmail-cf and see if you can find a README file. This file usually has all the file locations sendmail uses. However, if you are running somw whacked out version, they may have changed that directories location also.

I am using mac os x 10.4

This is why I have absolutely nothing to offer in this discussion.

 

[patrick99e99]

can't I just download a new version of sendmail and reinstall it to my ~/bin and use that instead of the one in usr/bin?

 

[mbrooks]

Of course you can. And in your current situation that would be the best option.

Hmm.. Ok, I downloaded sendmail, and read through all the readme files..

1. I went into the sendmail directory and did sh Build.

2. I went into the cf/cf directory and copied the generic-bsd4.4.mc as sendmail.mc-- Then I added these two lines to this file:

MASQUERADE_AS(`rufus.collinatorstudios.com')dnl
FEATURE(`masquerade_envelope')dnl

3. I did "m4 sendmail.mc > sendmail.cf"

4. I then went into the sendmail directory and did make, and then sudo make install.

I then had an /etc/mail folder, however, only a submit.cf file was there.. I did I test email, it worked, but my headers still showed localhost.. So I tried making another sendmail.cf again with:

MASQUERADE_AS(`rufus.collinatorstudios.com')dnl
FEATURE(`masquerade_envelope')dnl

I ran m4 and put the new sendmail.cf in the /etc/mail folder.

ran sendmail did another test.. same thing..

My headers show:

Received: from rufus (localhost [127.0.0.1])
by rufus.localhost (Postfix) with ESMTP id 95840921600

and

Received: (from patrick@localhost)
by rufus (8.13.8/8.13.8/Submit) id kB82RGv2018276

did I do something wrong?

[mbrooks]

Post your sendmail.mc please.

Do you have postfix running? Call me crazy but it is acting like you have postfix emulating sendmail. That is why none of the sendmail files existed.

 

[patrick99e99]

Hmm I checked into that..

rufus[patrick] /System/Library/LaunchDaemons> sudo service smtp stop
postfix/postfix-script: stopping the Postfix mail system


But then I sent myself another sendmail test and I received it.. The headers still say "postfix" and show:

Received: from rufus (localhost [127.0.0.1])
by rufus.localhost (Postfix) with ESMTP id C49BA922181
Received: (from patrick@localhost)
by rufus (8.13.8/8.13.8/Submit) id kB8JC3Lg019611

 

[RhythmAce]

Well there's nothing in the world you can do to sendmail to make postfix work. ;-)

 

[patrick99e99]

I'm sorry, I dont quite understand what you mean. I don't know a whole lot about postfix or sendmail...

So, are you saying that my headers should not be saying postfix?

It could be that my mailserver is receiving them with postfix?

because my header shows this:
Received: from spawn.easydns.com (smtp.easydns.com [205.210.42.52])
by star.collinatorstudios.com (Postfix) with ESMTP id 5CC96FF064

and star is my mailserver (a gentoo linux box).. I am really not sure how all this works. But I know for certain I ran the command to stop postfix, and I checked my activity monitor (top) and I saw nothing having to do with postfix running...

but the second received heading my email says:

Received: from rufus.localhost (pool-71-106-138-34.lsanca.dsl-w.verizon.net
[71.106.138.34])
by spawn.easydns.com (Postfix) with ESMTP id 2A1EC4E930


and there are two other 'received headers'.. which leads me to ask this question-- why are there four "received:" headers?

Postfix is a mail server just like sendmail. You are running postfix. Most 'other' mail servers emulate sendmail so that they can be used by existing scripts without having to be changed. What I was saying is that you should be asking this in the postfix forum, not sendmail. If you prefer sendmail, you will need to keep postfix from starting at bootup and have sendmail start in it's place. In my opinion, that would be a lot of work just to get 'localhost' out of your header.
