Postfix SMTP-relay server against Gmail on CentOS 6.4
- by Alex
I'm currently trying to setup an SMTP-relay server to Gmail with Postfix on a CentOS 6.4 machine, so I can send e-mails from my PHP scripts.
I followed this tutorial but I get this error output when trying to do a
sendmail [email protected]
Output:
tail -f /var/log/maillog

Here is my main.cf configuration, I tried a number of different options but nothing seems to work:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
inet_interfaces = localhost
inet_protocols = ipv4
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost
myhostname = host.local.domain
myorigin = $myhostname
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
relayhost = [smtp.gmail.com]:587
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
smtp_sasl_type = cyrus
smtp_tls_CAfile = /etc/ssl/certs/ca-bundle.crt
smtp_use_tls = yes
smtpd_sasl_path = smtpd
unknown_local_recipient_reject_code = 550
In the /etc/postfix/sasl_passwd files (sasl_passwd & sasl_passwd.db) I got the following (removed the real password, and replaced it with "password"):
[smtp.google.com]:587 [email protected]:password
To create the sasl_passwd.db file, I did that by running this command:
postmap hash:/etc/postfix/sasl_passwd
Do anybody got an idea why I can't seem to send an e-mail from the server?
Kind Regards Alex
