verizon dsl mail gateway and postfix on my linux box

Hi,

I have a question about the configuration of Postfix.

I'm running Ubuntu 6.06 and connected to the internet with Verizon DSL.
I just installed Postfix and I'm having an issue with mailing from my
machine. In /etc/mailname, I put "verizon.net". I assume this means
that I'm using the Verizon email gateway. When I send email to an
external email account, it works fine. The email looks like it was sent
from a verizon.net account (e.g. (E-Mail Removed)). However, when I
send email to a local account (e.g. "mail localuser"), it is sent to
(E-Mail Removed). I really want the local email sent to the local
account without appending "@verizon.net". Why is "@verizon.net" being
appended to local emails? How do I make it so that "@verizon.net" is
not appended?

Thanks very much for any help,
Don

Have you looked around on http://www.postfix.org/ for documentation/FAQ

Hmmm, a quick _man postfix_ does not mention /etc/mailname as a
configuration file.

I would add some keywords to the bottom of /etc/postfix/main.cf
to make postfix do what I want.

I assume you did update the bottom of aliases so that your user account would
receive root email.

$ tail -11 /etc/postfix/aliases | head -4


I run Mandriva Linux and cannot say what the postfix defaults are for
Ubuntu and I do not have /etc/mailname

I used virtual to tag local delivery, and copied canonical to canonical_sender
and canonical_recipient. With those and generic, I munge my body/header
from/to values to look like they come from my yahoo/hotmail accounts.

$ hostname
fw.home.invalid

$ tail -28 /etc/postfix/main.cf

# my appended changes to main.cf for my WAN node

default_destination_concurrency_limit = 1

mydestination = $myhostname localhost.$mydomain localhost $mydomain
mynetworks = 192.168.2.0/28, 127.0.0.0/8
relayhost = [smtp.comcast.net]
relay_domains =
inet_interfaces = all
unknown_local_recipient_reject_code = 550
smtp_host_lookup = dns, native


# local box users
virtual_alias_maps = hash:/etc/postfix/virtual

# Receiving: swap linux users into my ISP email users
# in header (from value
sender_canonical_maps = hash:/etc/postfix/canonical_sender

# Receiving: swap out header (to value example root
# recipient_canonical_maps = hash:/etc/postfix/canonical_recipient

# Sending: swap out email addresses that appear inside messages (From
smtp_generic_maps = hash:/etc/postfix/generic

#****** end main.cf ****************


$ hostname
wb.home.invalid

$ tail /etc/postfix/main.cf
# my changes appened to main.cf for my LAN nodes

myorigin = $myhostname
relay_domains =
relayhost = [fw.home.invalid]
inet_interfaces = $myhostname, localhost
unknown_local_recipient_reject_code = 550
smtp_host_lookup = dns, native

#********************** end main.cf ********************

"man mailname" tells you the story. Normally, if you put, say,
"verizon.net" in /etc/mailname, postfix would assume that
(E-Mail Removed) is local. But you probably set your mail client to
send your outgoing mail direct to your ISP's mail server so it doesn't
matter.
