Hi,

I would masquerade my Fdqn hostname (changing it with an another hostmame) when my server estabilishes an Smtp connection with an another mailserver.How can i do it??

Roberto Bolletta

yeah same problem for me. something with SMART_HOST define but i dont know where exactly.

I just went through masquerading my domaine name today. What is involved is editing the /etc/mail/linux.mc file which in turn is used to create the /etc/sendmail.cf file. I found it easier to utilize an administrator utility called Webmin. This utility can be downloaded from www.webmin.com.

Before doing anything make a backuo of the /etc/sendmail.cf and the /etc/mail/linux.mc files

Open Webmin and login with root.
From the left hand tree view expand "Servers"
Click on sendmail configuration
From the Sendmail Configuration screen select the "Sendmail M4 Configuration" option
The first screen lists the relevent entries in the linux.mc file. scroll to the bottom of the screen and click "Edit File Manually"

About 3/4 down the screen look for the following entries


Make the following changes



Once your edits are made click "Save" - You will be returned to the Linux.mc display screen.

Click on the "Rebuild Sendmail Configuration" button.

Once the rebuild is completed, return to sendmail configuration page.

Stop and then Start Sendmail

Test by sending an email to someone and see if the desired domaine name appears in the From address.

This process worked for me, individual mileage may vary.

Thanks for your answer Gcamp,but I tried to modify the mc file all the possibilities options ( i also tried to apply the examples I found in the sendmail documentation) but the problem remains....

Somebody help me!!
It is a SERIOUS problem for a mailserver!!!

Are you looking to change what Scalix says it's hostname is when you receive email, or are you looking to change what Sendmail says the hostname is when it sends mail?

Kev.

I'd also be interested in how I can change what sendmail says when sending a mail.

How can I do that?

Thanks

Chris

This isn't sendmail, this is Scalix, but the link here should help...

I believe the details for sendmail are already in this thread.

Kev.

this is the header that I get by sending an email:

I want that Scalix occurs to the other servers as "mail.atfservice.it" instead servermail.atf.locale (localhost [127.0.0.1]).

How can i do it?

You might try changing the /etc/mail/linux.mc to the following and then rebuilding the config file.

Received: from servermail.atf.locale (localhost [127.0.0.1])
by servermail.atf.locale (8.13.1/8.13.1) with ESMTP id l2DJCceX006707
for <roberto@mediaspot.net>; Tue, 13 Mar 2007 20:12:39 +0100
Received: from servermail.atf.locale (servermail.atf.locale [192.168.0.135])
by servermail.atf.locale (Scalix SMTP Relay 11.0.2.15)

There is little that either scalix or MASQUERADE_AS can do about this part.

You need a combination of 2 things:

1) edit the DNS entries on the name server to resolve the 192.168.0.135 to the name you want it to be. Since 192.168.x.x is a blessed network, I'm assuming you are hosting the server behind a firewall and redirecting the ports. So try option 2.
2) edit /etc/hosts and put an entry of the form
192.168.0.135 mail.atfservice.it mail

Let us know what happens.

You also need to deal with the servermail.atf.locale entry, which also most likely also comes from /etc/hosts. Something like this
127.0.0.1 servermail.atf.locale

This can be a little trick when changed, because it may break part of the server that relies or uses the "servermail.atf.locale" string. But if you must, try this:
127.0.0.1 mail.atfservice.it servermail.atf.locale
