I had postfix running on my machine(comes with centos minimal), but today I configured it to use my domain for the sake of example this is my domain name
example.com . Here is my config :
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 header_checks = regexp:/etc/postfix/header_checks html_directory = no inet_interfaces = all inet_protocols = ipv4 mail_owner = postfix mailbox_size_limit = 1073741824 mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man message_size_limit = 10485760 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = example.com myhostname = mail.example.com mynetworks = 127.0.0.0/8 mynetworks_style = host myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES relayhost = smtp.$mydomain sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_banner = $myhostname ESMTP $mail_name smtpd_client_restrictions = permit_mynetworks,reject_unknown_client,permit smtpd_recipient_restrictions = permit_mynetworks,permit_auth_destination,permit_sasl_authenticated,reject unknown_local_recipient_reject_code = 550
I need one email account to be able to send emails (password retrievals etc.). I read today somewhere that if you create unix account postfix will recognize it as email address so if your account username was
ant your email would be
So I tested that and tried to send email to
firstname.lastname@example.org and I successfully received mail.
When I try to send the email with ant task script, I'm not able to connect :
Failed messages: javax.mail.MessagingException: Could not connect to SMTP host: mail.example.com, port: 25; nested exception is: java.net.ConnectException: Connection timed out: connect
What am I missing here?
I'm able to telnet to localhost :
Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 mail.example.com ESMTP Postfix
