Postfix/POP3/IMAP

According to the perfect setup for debian tutorial:
In order to install Postfix with SMTP-AUTH and TLS as well as a POP3 server that also does POP3s (port 995) and an IMAP server that is also capable of IMAPs (port 993) do the following steps:

apt-get install postfix postfix-tls libsasl2 sasl2-bin libsasl2-modules ipopd-ssl uw-imapd-ssl (1 line!) this took more than 1 line...is that a problem?

<- pop3 and pop3s
<- No
<- Internet Site
<- NONE
<- server1.example.com
<- server1.example.com, localhost.example.com, localhost
<- No
when i got to this point, i only got prompts for the 1st four lines.

postconf -e 'smtpd_sasl_local_domain ='
postconf -e 'smtpd_sasl_auth_enable = yes'
postconf -e 'smtpd_sasl_security_options = noanonymous'
postconf -e 'broken_sasl_auth_clients = yes'
postconf -e 'smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination'
postconf -e 'inet_interfaces = all'
echo 'pwcheck_method: saslauthd' >> /etc/postfix/sasl/smtpd.conf
echo 'mech_list: plain login' >> /etc/postfix/sasl/smtpd.conf

I don't know where to put the above information...

mkdir /etc/postfix/ssl
cd /etc/postfix/ssl/
openssl genrsa -des3 -rand /etc/hosts -out smtpd.key 1024
chmod 600 smtpd.key
openssl req -new -key smtpd.key -out smtpd.csr
openssl x509 -req -days 3650 -in smtpd.csr -signkey smtpd.key -out smtpd.crt
openssl rsa -in smtpd.key -out smtpd.key.unencrypted
mv -f smtpd.key.unencrypted smtpd.key
openssl req -new -x509 -extensions v3_ca -keyout cakey.pem -out cacert.pem -days 3650

i'm assuming these are shell command....

postconf -e 'smtpd_tls_auth_only = no'
postconf -e 'smtp_use_tls = yes'
postconf -e 'smtpd_use_tls = yes'
postconf -e 'smtp_tls_note_starttls_offer = yes'
postconf -e 'smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key'
postconf -e 'smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt'
postconf -e 'smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem'
postconf -e 'smtpd_tls_loglevel = 1'
postconf -e 'smtpd_tls_received_header = yes'
postconf -e 'smtpd_tls_session_cache_timeout = 3600s'
postconf -e 'tls_random_source = dev:/dev/urandom'

again, i'm not sure where to put this information.

after this section, it shows what the /etc/postfix/main.cf file should look like....i'm not sure where to find the file to view it.....again, i'm assuming I would use the easy editor.....

sorry for the long post, but i'm really new at this and confused.....

 

Yes shell commands

You can add the one at a time to the shell.

The you can use vi /etc/postfix/main.cf to see the output.

NOTE: pay attention to this line though:

smtpd_sasl_local_domain = $myhostname

I'm not sure why but I had to add $myhostname manually. To be quite frank I don't even know if it makes a difference.
