Another sendmail problem

Posted on 1998-10-14

On Linux RedHat 5.1 I would like to masquerade the real email address (like me@machine_real_name.local) with my the official name of my organization (First_Last@my_organization.com).

Is this possible using linuxconf?

I can change the real hostname with the official domain name, but not the user name.

Thanks in advance.

To masquerade your machine real name, kook for the option DM in your /etc/sendmail.cf file and change it to:

DMmy_organization.com


After that, restart your sendmail in order to changes take effect.

The only way i know to masquerade the first part of e-mail address is through aliases. Edit the file /etc/aliases
and insert one line per user:

user: First_Last

Or, if all users in your /etc/passwd have at least two names (first, last) you can generate this file using the commandline:

cut -f1,5 -d':' /etc/passwd | sed s,":\(.*\) .* \(.*\)$",": \1_\2", >> /etc/aliases

After that, execute the commandline:

# newaliases

You'll have also to reconfigure all your e-mail client software to the new masquerade e-mail adressesses :-/

DMmy_organization.com is right, but it is only for the domain. With /etc/aliases I can create an incoming alias but not an outcoming alias.

Using the mailconf module of the linuxconf, I succed in changing the account name and domain name of the mails posted by other programs (like Eudora from windows) to the 25 port but not the user name of the localhost becouse it does not fully qualify when it send mails.

Take a look at the book Sendmail(the bat book)from O'Reilly & Associates, Inc.

at page 262 it talk about the feature genericstable, which can change the mail address.

Ok, the feature genericstable is the right one. On RedHat distribution it is a bit difficult to make changes in sendmail configuration without using LinuxConf.

Thank you.
