Sendmail -bv user unkown


Hello

I am having an issue with sendmail. It is not recognizing the users with the full domain name.

If I run the sendmail -bt, then do the /try smtp userID, is shows the ID with the proper name and domain.


Though if I run the sendmail -bv command I get the following error.

[root@lks ~]# sendmail -bv david.gill@DOMAIN
david.gill@DOMAIN... deliverable: mailer esmtp, host DOMAIN, user david.gill@DOMAIN
[root@lks ~]# sendmail -bv david.gill@DOMAIN.com
david.gill@DOMAIN.com... User unknown

THANKS!

Odd since it should be the other way around. Since when do you have this error? What changed in sendmail config between initial state and now?

When I add the masqurading line into the .mc file.

Though if I take out the masqurading line, I get a 550 5.7.1 reject mail error.

Good question. Sorry for not including that.

Sorry for late reply. So your e-mail isn't accepted by remote MTAs (smarthost?) and your masquerading lines don't work well. Maybe posting what you changed and added could help.

It changes when I remove the MASQUERADE_AS(`DOMAIN.com')dnl. It changes from unknown user to rejected 550 5.7.1.

I don't understand why it accepts from remote MTAs then not when masquerading is disabled. Masquerading doesn't have anything to do with rejecting mail. I thought the server was sapose to accept everything unless it was labeled reject in the access file.

Here is my .mc file________________________________________________________

First of all I think it would be best if you filled in your distro inf in your profile, and if that doesn't reflect this particular machine post its distro, version and sendmail version here.

I think you're confusing things. Remote MTAs sending e-mail to your MTA doesn't have anything to do with masquerading. Masquerading affects how remote MTAs view e-mail *your* MTA sends. "550 5.7.1" means "relaying denied" and unless you post output (of say 'sendmail -d1-20.99 -bv david.gill@lkelectric.com') I can't see how this relates.

Your sendmail.mc looks *way* too sparse to me. As far as I know if you use DOMAIN() it should be DOMAIN(`generic')dnl (as in the "generic.m4" and if you use a domain.m4 (which in your case looks like a plain copy of "generic.m4" with partial masq directives tacked on?) you should name it to yourdomain.m4 and use that, so: DOMAIN(`myrealdomainname')dnl. How, or better: using what documentation, did you configure all of this I wonder?

I suggest you remove the "connect" from localhost and domain since you want to be able to send from and to, so that'll be plain "localhost.localdomain RELAY". On the other hand, for other domains like yahoo.com I think it would be more clear if you *explicitly* set what you want to do. You want to relay *to* but not *from* that domain (even though that's useless since they wouldn't ever use your MX), so use "To:yahoo.com RELAY".


I'm no Sendmail guru but I think you want to go back to the drawingboard, read some sendmail docs and build your sendmail.mc from some template because it does not look complete to me. A very basic .mc file, listening on localhost only, w/o certs, and stuff should look something like this:
Code:
divert(-1)dnl
include(`/usr/share/sendmail-cf/m4/cf.m4')dnl
VERSIONID(`replace_my linux sendmail template')dnl

* If you're going to test configurations be aware you can run Sendmail on another port with another config. For example if your M4 generated config is aptly named "test" and the port is 1234, run: 'sendmail - Ctest.cf -bd -oOP=1234'.

Up front, thanks for the help.

I updated my profile with distro information. It is RedHat 5 Enterprise.

Here is my sendmail version info.
[root@lks ~]# rpm -q sendmail
sendmail-8.13.8-2.el5

Just to make certain everything on my side is good, could you check that first quote, because in it I stated that masquerading doesn't have anything to do with rejecting mail.

Also I included the output of the 'sendmail -d1-20.99 -bv david.gill@DOMAIN.com' command. It is at the bottom. My DNS works ok...

In my .mc file I removed the actual name of my domain file and replaced it with DOMAIN...

As far as the .mc file I think you may be right for some things, I'm gona look through those commands and add the ones which aren't defaults or already included in .m4 files like domain.m4 and distro.m4.

With the access file, I've found next to no good documentation on it. Do you have any suggestions other than the sendmail readme file? With that file I could REALLY use some documentation because that is the one thing that I have many questions on with sendmail.

The documentation I've been using to set this up is Craig Hunt's 'Linux Network Servers'.

Reviewing your earlier threads, this doesn't involve addressing of case sensitive /etc/passwd usernames "DavidGill" or "David.Gill" that should really read "davidgill" "david.gill", right?

Holy poopie dipers.

No you are totally right. I just created a user ID with all lower case, and it resolved perfectly fine!

I though my generics table which has the proper cases would resolve that?!

If you don't mind saving me about two hours worth of research, how do I get it to work with the capitols. Should I have used VirtualUserTables?

Well that's not resolution but case sensitivity dictated by the LDA for ya. AFAIK genericstable is for username to e-mail (outbound: davidgill DavidGill) translation and virtusertable for e-mail to username (inbound: DavidGill@somehost davidgill). Wrt documentation there's lots in different places: the sendmail-doc package, sial.org and other sites have more Sendmail information on-line than I'll ever read and then there's "the Bat Book" aka O'Reilly's "Using Sendmail"...

Well, I'm using procmail as my LDA. I don't need to config it directly though. Sendmail has a feature to add.

Thanks also for the quick edication on virtual user tables. I've got that up and it is testing fine...

To get sendmail to accept capitals on user IDs refer to http://www.sendmail.org/faq/section4.

Thank you again for the help!!!

Everything is up and running fine.
