ubuntu postfix setup on verizon fios

It took me more googling than it should have to figure out how to setup a home server to relay email through verizon's smtp server. Here's what I did.

First, you need a fully qualified domain name (FQDN). This can be set in ubuntu by:

sudo /bin/hostname myserver.domain.com

Next, install postfix and mailutils:

sudo apt-get install postfix mailutils

Set up your /etc/postfix/main.cf. Here's what mine looks like:

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

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

readme_directory = no

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
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 = myserver.domain.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = myserver.domain.com, myserver, localhost.localdomain, localhost

relayhost = [outgoing.verizon.net]
smtp_connection_cache_destinations = outgoing.verizon.net
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = static:username@verizon.net:password
smtp_sasl_security_options = noanonymous
default_destination_concurrency_limit = 4
soft_bounce = yes

mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

restart postfix and you should be all set

/etc/init.d/postfix restart

to test from the command line, use mail

myserver> mail email@isp.com
