Postfix email issues

Webmin
1

For the first time I decided to get an self managed VPS. It’s gone pretty good so far. I’m using Virtualmin on Ubuntu 12.04 with Postfix as my mail server. I have noticed an issue that seems to be sending all my emails to peoples spam folders. Some header content is missing.

A sample header

from: Site Name webmaster@com
to: username emailaddress@com
date: Wed, May 8, 2013 at 11:31 PM
subject: Test Email
mailed-by: com

As you can see everything shows as from or to “com” with no domain. Anyone have any ideas? I obviously missed something along the way.

Howdy,

What is the output of these two commands:

hostname postconf -n
3

Here is the output

~$ sudo hostname

mysite

:~$ postconf -n

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
allow_percent_hack = no
append_dot_mydomain = no
biff = no
config_directory = /etc/postfix
home_mailbox = Maildir/
inet_interfaces = all
inet_protocols = all
mailbox_command = procmail -a “$EXTENSION”
mailbox_size_limit = 0
masquerade_domains = $mydomain
mydestination = mysite.com, localhost.com, localhost, mysite, myothersite
myhostname = mysite.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mynetworks_style = host
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost =
sender_bcc_maps = hash:/etc/postfix/bcc
sender_dependent_default_transport_maps = hash:/etc/postfix/dependent
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
smtpd_helo_required = yes
smtpd_recipient_restrictions = permit_mynetworks reject_unauth_destination permit_inet_interfaces
smtpd_sasl_auth_enable = yes
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_mandatory_ciphers = high
smtpd_tls_mandatory_protocols = SSLv3, TLSv1
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_maps = hash:/etc/postfix/virtual

Okay, one last question – what are the contents of the file “/etc/mailname”?

mysite.com

Anyone have any ideas? My forum is pretty much crippled until I can fix this.

Here is the entire header if it helps

This is a multi-part message in MIME format.

I followed some of the leads in the following thread and found that some of those files did have my old hostname. Fixed, restarted, still the same. What’s really confusing is why does the receivers domain get removed?

After doing all the above and still not working I took the .com off of myhostname = mysite.com and now it works. shrugs
