Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm kinda a noob as a server admin so please bear with me. I've installed postfix mail server and everything is working fine but the 'from' box is displaying I want to set it up so it displays instead of IP. I just hope you know what I mean. My in postfix folder looks like this:

    # See /usr/share/postfix/ for a commented, more complete version

# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# TLS parameters
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

myhostname = mail.thevinylfactory
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination =, thevinylfactory, localhost.localdomain, localhost
relayhost = 
mynetworks = [::ffff:]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

Can anyone help me with this one? If you need any more details please let me know. Thanks in advance!

  1. Set your hostname correctly Read more here about changing domainname/hostname

  2. Look what you have in /etc/mailname and modify accordingly

  3. Don't forget about /etc/hosts & reverse DNS.

After everything is in place, restart postfix.
