# alternatives --config mta

There are 2 programs which provide 'mta'.

Selection Command ----------------------------------------------- *+ 1 /usr/sbin/sendmail.sendmail 2 /usr/sbin/sendmail.postfix

but I shutdown both them, I install kerio mailserver system as MTA, and listen on port 25.

...

Hi,

I installed a CentOS 4.7 server, the system information is:

# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=mail.domain11.com

# hostname mail.domain11.com

#echo "test " | mail -s "test mail" someone@domain22.com

I would like to receive mail is root@domain11.com, but I received is root@mail.domain11.com

How to correct it?

(I've tested there is no problem in CentOS 5.2)

Best regards

What MTA are you using? Sendmail? Postfix? Exim? Qmail? Courier? _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Kerio has it's own admin interface that deals with these sort of problems, did you install it?

and, this is a Kerio configuration problem, not a CentOS problem. Take it up with Kerio.

with sendmail, you need to set some configuration options to masquerade the host if you want locally submitted mail to be 'from' the domain name.

typically, in /etc/mail/sendmail.mc, the line...

MASQUERADE_AS(`mydomain.com')

then run `make` in that directory. for this to work correctly, you need to install the sendmail-cf package

with any other mail client, its similar.

Good, Solution:

# vi /etc/mail/sendmail.mc

add this line : EXPOSED_USER(`Mailer-Daemon')

# cd /etc/mail # make # service sendmail restart

HOW?

With sendmail try to remove root from EXPOSED_USER list.
