---|---|
Only try this if you know what you’re doing. |
I took the information from this page and modified them slightly for Fedora 14 / Amahi 6.
First of all, install postfix and remove sendmail:
bash code |
---|
yum -y install postfix yum -y remove sendmail
|
Openssl and openssl-perl are needed to generate certificates and create SSL connections to GMail
Openssl should be installed already, but to be sure:
bash code |
---|
yum -y install openssl openssl-perl
|
A Certificate Authority is needed to create the necessary certificates. You can skip the next paragraph if you already have one:
bash code |
---|
cd /etc/pki/tls/misc ./CA.pl –newca
|
- You will be prompted for the file name, hit enter to create a new CA.
- You will need to enter a passphrase next, be sure to remember it.
- Choose the Country Name, State or Province Name, Locality Name, Organization Name, and Organizational Unit Name to your liking. Be sure to remember the values, they will be needed in the key creation later.
- For the Common Name, type “CA” (without quotes).
- Take defaults for everything else and when prompted enter the passphrase from above.
Now a key that is sent to Gmail to start the SSL encryption will be created:
bash code |
---|
cd /etc/pki/tls mkdir gmail_relay cd gmail_relay openssl genrsa -out server.key 1024 openssl req -new -key server.key -out server.csr
|
You will be prompted for country etc. like when creating the CA. Enter the same values.
As Common Name, now enter the name of your server, FQDN or not, your choice.
bash code |
---|
openssl ca -out server.pem -infiles server.csr
|
You will need to enter your passphrase again at this point.
When asked if you want to sign the key, answer yes, same when asked if to commit it.
Add the following to the bottom of the file /etc/postfix/main.cf. You do not need to change anything else in it, as the last setting for any option is the one that is saved.

Create /etc/postfix/sasl_passwd file with your Gmail login credentials that looks like below:
Text |
---|
gmail-smtp.l.google.com user@gmail.com:password smtp.gmail.com user@gmail.com:password
|
Obviously, you need to change user to your username and password to your gmail password.
Create the password database:
bash code |
---|
postmap hash:/etc/postfix/sasl_passwd
|
Protect the files with your Gmail login data:
bash code |
---|
chmod 600 /etc/postfix/sasl_passwd chmod 600 /etc/postfix/sasl_passwd.db chown postfix /etc/postfix/sasl_passwd chown postfix /etc/postfix/sasl_passwd.db
|
Restart Postfix
bash code |
---|
/etc/init.d/postfix restart
|
Now try sending a mail, it should reach your Gmail account.
