Hi,

I installed mail server using postfix dovecot spamassassin squirrelmail;. I can able to send and receive the mails. But my mail id is showing as username@hostname.domain name instead of username@domainname.
Example:
username:test
hostname:mailserver
domainname: xyz.com
then the mail id shold be test@xyz.com
but for me it showing as test@mailserver.uceou.edu......

here is my postfix configuration details..
/etc/postfix/main.cf
________________________________________________________________________
myhostname = mailserver.xyz.com
myorigin = $mydomain
inet_interfaces = all
mydestination = $mydomain, $myhostname, localhost.$mydomain,localhost xyz.com
local_recipient_maps = unixasswd.byname $alias_maps
mynetworks_style = host

________________________________________________________________________
here is my /etc/hosts file
________________________________________________________________________

127.0.0.1 mailserver mailserver localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
________________________________________________________________________


With the above configuration i was able to send and receive the mails..




Thanks in advance.

Add an MX record to your DNS server.

Example (for bind):

If you want to rewrite mailserver.xyz.com to just xyz.com, you have to use masquerade_domains:
in main.cf
