Postfix

[amanda099]

I'm trying to install Postfix on my Ubuntu 10.4 using
help.ubuntu.com/community/Po...asicSetupHowto

I'm following the instruction closely. When I test my default installation using telnet localhost 25, I get the following:

telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

Please help me out ! What have I done wrong ?

Have you defined "mynetworks = 127.0.0.0/8" or "mynetworks = 127.0.0.1/32"?

I use the default 127.0.0.0/8. I don't know the difference

Either one should be fine. What about your "inet_interfaces" parameter. By default, it should be set to "= all", which should work, but it might be worth checking. If it is not set to all, try setting it to that, restarting Postfix, and trying again.

hi nplusplus, this is my main.cf:

# See /usr/share/postfix/main.cf.dist 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_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 = luckyseven-desktop
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = luckyseven-desktop, localhost.localdomain, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128

I can now do telnet localhost 25 and it works as described in the guide.
Now I come to: "Adding your local domains to postfix". How can I configure mydestination
In the guide, it says:
sudo postconf -e "mydestination = mail.fossedu.org, localhost.localdomain, localhost, yourdomain.com"

Do you know what you did to fix your original problem?

As far as adding local domains, I have never used the postconf -e method. I normal just edit main.cf and reload/restart (depending on what is recommended in the postfix documentation).

For more general help, you might check out The Postfix Home Page.

I'm not very sure how.

and How can I identify my local domain name ?
